We provide a baseline for a redshift-independent star formation efficiency model to which observations and models can be compared. Our model assigns a star formation rate (SFR) to each dark matter halo based on the growth rate of the halo and a redshift-independent star formation efficiency. The dark matter halo accretion rate is obtained from a high-resolution N-body simulation in order to capture the stochasticity in accretion histories and to obtain spatial information for the distribution of galaxies. The halo mass dependence of the star formation efficiency is calibrated at z = 4 by requiring a match to the observed UV LF at this redshift. The model then correctly predicts the observed UV LF at z = 5–10. We present predictions for the UV luminosity and stellar mass functions, JWST number counts, and SFHs. In particular, we find a stellar-to-halo mass relation at z = 4–10 that scales with halo mass at M h < 1011 M as M ∝ M h 2, with a normalization that is higher than the relation inferred at z = 0. The average SFRs increase as a function of time to z = 4, although there is significant scatter around the average: about 6% of the z = 4 galaxies show no significant mass growth. Using these SFHs, we present redshift-dependent UV-to-SFR conversion factors, mass return fractions, and mass-to-light ratios for different initial mass functions and metallicities, finding that current estimates of the cosmic SFR density at z ∼ 10 may be overestimated by ∼0.1–0.2 dex. %3 10.3847/1538-4357/aae8e0 %= eprint: arXiv:1806.03299 %@ 0004-637X %0 Electronic Article %T A Deep Learning Approach to Galaxy Cluster X-ray Masses %A Ntampaka, M. %A ZuHone, J. %A Eisenstein, D. %A Nagai, D. %A Vikhlinin, A. %A Hernquist, L. %A Marinacci, F. %A Nelson, D. %A Pakmor, R. %A Pillepich, A. %A Torrey, P. %A Vogelsberger, M. %B arXiv e-prints %V 1810 %D 2018 %8 October 1, 2018 %K Astrophysics - Cosmology and Nongalactic Astrophysics %U http://adsabs.harvard.edu/abs/2018arXiv181007703N %Z 10 pages, 6 figures, submitted to ApJ %X We present a machine-learning approach for estimating galaxy cluster masses from Chandra mock images. We utilize a Convolutional Neural Network (CNN), a deep machine learning tool commonly used in image recognition tasks. The CNN is trained and tested on our sample of 7,896 Chandra X-ray mock observations, which are based on 329 massive clusters from the IllustrisTNG simulation. Our CNN learns from a low resolution spatial distribution of photon counts and does not use spectral information. Despite our simplifying assumption to neglect spectral information, the resulting mass values estimated by the CNN exhibit small bias in comparison to the true masses of the simulated clusters (-0.02 dex) and reproduce the cluster masses with low intrinsic scatter, 8% in our best fold and 12% averaging over all. In contrast, a more standard core-excised luminosity method achieves 15-18% scatter. We interpret the results with an approach inspired by Google DeepDream and find that the CNN ignores the central regions of clusters, which are known to have high scatter with mass. %= eprint: arXiv:1810.07703 %0 Electronic Article %T A High-Fidelity Realization of the Euclid Code Comparison $N$-body Simulation with Abacus %A Garrison, Lehman H. %A Eisenstein, Daniel J. %A Pinto, Philip A. %B arXiv e-prints %V 1810 %D 2018 %8 October 1, 2018 %K Astrophysics - Cosmology and Nongalactic Astrophysics; Astrophysics - Instrumentation and Methods for Astrophysics; Physics - Computational Physics %U http://adsabs.harvard.edu/abs/2018arXiv181002916G %Z 13 pages, 8 figures. Submitted to MNRAS %X We present a high-fidelity realization of the cosmological $N$-body simulation from the Schneider et al. (2016) code comparison project. The simulation was performed with our Abacus $N$-body code, which offers high force accuracy, high performance, and minimal particle integration errors. The simulation consists of $2048^3$ particles in a $500\ h^{-1}\mathrm{Mpc}$ box, for a particle mass of $1.2\times 10^9\ h^{-1}\mathrm{M}_\odot$ with $10\ h^{-1}\mathrm{kpc}$ spline softening. Abacus executed 1052 global time steps to $z=0$ in 107 hours on one dual-Xeon, dual-GPU node, for a mean rate of 23 million particles per second per step. We find Abacus is in good agreement with Ramses and PKDGrav and less so with Gadget-3. We validate our choice of time step by halving the step size and find sub-percent differences in the power spectrum and 2PCF at nearly all measured scales, with $<0.3\%$ errors at $k<10\ \mathrm{Mpc}^{-1}h$.

We describe the methodology of four different generalizations: satellite distribution generalization, velocity bias, closest approach distance generalization, and assembly bias. We showcase the signatures of these generalizations in the 2-point correlation function (2PCF) and the squeezed 3-point correlation function (squeezed 3PCF). We identify generalized HOD prescriptions that are nearly degenerate in the projected 2PCF and demonstrate that these degeneracies are broken in the redshift-space anisotropic 2PCF and the squeezed 3PCF. We also discuss the possibility of identifying degeneracies in the anisotropic 2PCF and further demonstrate the extra constraining power of the squeezed 3PCF on galaxy-halo connection models. We find that within our current HOD framework, the anisotropic 2PCF can predict the squeezed 3PCF better than its statistical error. This implies that a discordant squeezed 3PCF measurement could falsify the particular HOD model space. Alternatively, it is possible that further generalizations of the HOD model would open opportunities for the squeezed 3PCF to provide novel parameter measurements.

We present tests using the dark matter density field in both real and redshift space generated from an N-body simulation. In redshift space at z = 0.5, we find that the reconstructed displacement field using our iterative method are more than 80 per cent correlated with the true displacement field of the dark matter particles on scales k < 0.10 h Mpc-1. Furthermore, we show that the two-point correlation function of our reconstructed density field matches that of the initial density field substantially better, especially on small scales (<40 h-1 Mpc). Our redshift-space results are improved if we use an anisotropic smoothing so as to account for the reduced small-scale information along the line of sight in redshift space. %3 10.1093/mnras/sty1203 %= eprint: arXiv:1804.04738 %@ 0035-8711 %0 Journal Article %T A practical computational method for the anisotropic redshift-space three-point correlation function %A Slepian, Zachary %A Eisenstein, Daniel J. %+ AA(Einstein Fellow, Lawrence Berkeley National Laboratory, 1 Cyclotron Road, Berkeley, CA 94720, USA; Berkeley Center for Cosmological Physics, University of California, Berkeley, CA 94720, USA), AB(Harvard-Smithsonian Center for Astrophysics, 60 Garden Street, Cambridge, MA 02138, USA) %B Monthly Notices of the Royal Astronomical Society %V 478 %D 2018 %8 August 1, 2018 %P 1468-1483 %K cosmology: observations; distance scale; large-scale structure of Universe %U http://adsabs.harvard.edu/abs/2018MNRAS.478.1468S %X We present an algorithm enabling computation of the anisotropic redshift-space galaxy three-point correlation function (3PCF) scaling as N2, with N the number of galaxies. Our previous work showed how to compute the isotropic 3PCF with this scaling by expanding the radially binned density field around each galaxy in the survey into spherical harmonics and combining these coefficients to form multipole moments. The N2 scaling occurred because this approach never explicitly required the relative angle between a galaxy pair about the primary galaxy. Here, we generalize this work, demonstrating that in the presence of azimuthally symmetric anisotropy produced by redshift-space distortions (RSD), the 3PCF can be described by two triangle side lengths, two independent total angular momenta, and a spin. This basis for the anisotropic 3PCF allows its computation with negligible additional work over the isotropic 3PCF. We also present the covariance matrix of the anisotropic 3PCF measured in this basis. Our algorithm tracks the full 5D redshift-space 3PCF, uses an accurate line of sight to each triplet, is exact in angle, and easily handles edge correction. It will enable use of the anisotropic large-scale 3PCF as a probe of RSD in current and upcoming large-scale redshift surveys. %3 10.1093/mnras/sty1063 %= eprint: arXiv:1709.10150 %@ 0035-8711 %0 Electronic Article %T Large Covariance Matrices: Accurate Models Without Mocks %A O'Connell, Ross %A Eisenstein, Daniel J. %B arXiv e-prints %V 1808 %D 2018 %8 August 1, 2018 %K Astrophysics - Cosmology and Nongalactic Astrophysics %U http://adsabs.harvard.edu/abs/2018arXiv180805978O %Z Submitted to MNRAS %X Covariance matrix estimation is a persistent challenge for cosmology. We focus on a class of model covariance matrices that can be generated with high accuracy and precision, using a tiny fraction of the computational resources that would be required to achieve comparably precise covariance matrices using mock catalogues. In previous work, the free parameters in these models were determined using sample covariance matrices computed using a large number of mocks, but we demonstrate that those parameters can be estimated consistently and with good precision by applying jackknife methods to a single survey volume. This enables model covariance matrices that are calibrated from data alone, with no reference to mocks. %= eprint: arXiv:1808.05978 %0 Conference Paper %T Overview of the Dark Energy Spectroscopic Instrument %A Martini, Paul %A Bailey, Stephen %A Besuner, Robert W. %A Brooks, David %A Doel, Peter %A Edelstein, Jerry %A Eisenstein, Daniel %A Flaugher, Brenna %A Gutierrez, Gaston %A Harris, Stewart E. %A Honscheid, Klaus %A Jelinsky, Patrick %A Joyce, Richard %A Kent, Stephen %A Levi, Michael %A Prada, Francisco %A Poppett, Claire %A Rabinowitz, David %A Rockosi, Constance %A Cardiel Sas, Laia %A Schlegel, David J. %A Schubnell, Michael %A Sharples, Ray %A Silber, Joseph H. %A Sprayberry, David %A Wechsler, Risa %+ AA(The Ohio State Univ.

This reduces the shot noise that would otherwise affect the autocorrelation of the sparse spectroscopic map. As a proof of principle, we make the first on-sky application of this method to a sparse sample defined as the z > 0.6 tail of the Sloan Digital Sky Survey's (SDSS) BOSS/CMASS sample of galaxies and a dense photometric sample from SDSS DR9. We find a 2.8σ preference for the BAO peak in the cross-correlation at an effective z = 0.64, from which we measure the angular diameter distance DM(z = 0.64) = (2418 ± 73 Mpc)(rs/rs, fid). Accordingly, we expect that using this method to combine sparse spectroscopy with the deep, high-quality imaging that is just now becoming available will enable higher precision BAO measurements than possible with the spectroscopy alone. %3 10.1093/mnras/sty870 %= eprint: arXiv:1709.03514 %@ 0035-8711 %0 Journal Article %T They Might Be Giants: An Efficient Color-based Selection of Red Giant Stars %A Conroy, Charlie %A Bonaca, Ana %A Naidu, Rohan P. %A Eisenstein, Daniel J. %A Johnson, Benjamin D. %A Dotter, Aaron %A Finkbeiner, Douglas P. %+ AA(Harvard-Smithsonian Center for Astrophysics, Cambridge, MA 02138, USA 0000-0002-1590-8551), AB(Harvard-Smithsonian Center for Astrophysics, Cambridge, MA 02138, USA 0000-0002-7846-9787), AC(Harvard-Smithsonian Center for Astrophysics, Cambridge, MA 02138, USA), AD(Harvard-Smithsonian Center for Astrophysics, Cambridge, MA 02138, USA), AE(Harvard-Smithsonian Center for Astrophysics, Cambridge, MA 02138, USA), AF(Harvard-Smithsonian Center for Astrophysics, Cambridge, MA 02138, USA 0000-0002-4442-5700), AG(Harvard-Smithsonian Center for Astrophysics, Cambridge, MA 02138, USA 0000-0003-2808-275X) %B The Astrophysical Journal Letters %V 861 %D 2018 %8 July 1, 2018 %K Galaxy: halo; Galaxy: kinematics and dynamics %U http://adsabs.harvard.edu/abs/2018ApJ...861L..16C %X We present a color-based method for identifying red giants based on the Pan-STARRS grz and WISE W1 and W2 photometry. We utilize a subsample of bright stars with precise parallaxes from Gaia’s second data release (DR2) to verify that the color-based selection reliably separates dwarfs from giants. The selection is conservative in the sense that contamination is small (≈30%) but not all giants are included (the selection primarily identifies K giants). The color-based selection can be applied to stars brighter than W1 ≈ 16, more than two magnitudes fainter than techniques relying on shallower 2MASS photometry. Many streams and clouds are visible in the resulting sky maps, especially when binned by Gaia DR2 proper motions, including the Sagittarius stream, the Hercules–Aquila Cloud, the Eastern Banded Structure, Monoceros, and the Virgo Overdensity. In addition to the characterization of new and known stellar streams, we expect that this method for selecting red giants will enable detailed analysis of the diffuse stellar halo to distances exceeding 100 kpc. %3 10.3847/2041-8213/aacdf1 %= eprint: arXiv:1805.05954 %@ 0004-637X %0 Journal Article %T The clustering of galaxies in the completed SDSS-III Baryon Oscillation Spectroscopic Survey: theoretical systematics and Baryon Acoustic Oscillations in the galaxy correlation function %A Vargas-Magaña, Mariana %A Ho, Shirley %A Cuesta, Antonio J. %A O'Connell, Ross %A Ross, Ashley J. %A Eisenstein, Daniel J. %A Percival, Will J. %A Grieb, Jan Niklas %A Sánchez, Ariel G. %A Tinker, Jeremy L. %A Tojeiro, Rita %A Beutler, Florian %A Chuang, Chia-Hsun %A Kitaura, Francisco-Shu %A Prada, Francisco %A Rodríguez-Torres, Sergio A. %A Rossi, Graziano %A Seo, Hee-Jong %A Brownstein, Joel R. %A Olmstead, Matthew %A Thomas, Daniel %+ AA(Instituto de Física, Universidad Nacional Autónoma de México, Apdo.

We perform a detailed study of the impact on BAO measurements from choices in the methodology such as fiducial cosmology, clustering estimators, random catalogues, fitting templates, and covariance matrices. The theoretical systematic uncertainties in BAO parameters are found to be 0.002 in the isotropic dilation α and 0.003 in the quadrupolar dilation ɛ. The leading source of systematic uncertainty is related to the reconstruction techniques. Theoretical uncertainties are sub-dominant compared with the statistical uncertainties for BOSS survey, accounting 0.2σstat for α and 0.25σstat for ɛ (σα, stat ˜ 0.010 and σɛ, stat ˜ 0.012, respectively). We also present BAO-only distance scale constraints from the anisotropic analysis of the correlation function. Our constraints on the angular diameter distance DA(z) and the Hubble parameter H(z), including both statistical and theoretical systematic uncertainties, are 1.5 per cent and 2.8 per cent at zeff = 0.38, 1.4 per cent and 2.4 per cent at zeff = 0.51, and 1.7 per cent and 2.6 per cent at zeff = 0.61.

The systematic error budget concerning the methodology on post-reconstruction BAO analysis presented here is used in Alam et al. to produce the final cosmological constraints from BOSS. %3 10.1093/mnras/sty571 %= eprint: arXiv:1610.03506 %@ 0035-8711 %0 Journal Article %T The Abacus Cosmos: A Suite of Cosmological N-body Simulations %A Garrison, Lehman H. %A Eisenstein, Daniel J. %A Ferrer, Douglas %A Tinker, Jeremy L. %A Pinto, Philip A. %A Weinberg, David H. %+ AA(Harvard-Smithsonian Center for Astrophysics, 60 Garden St., Cambridge, MA 02138, USA 0000-0002-9853-5673), AB(Harvard-Smithsonian Center for Astrophysics, 60 Garden St., Cambridge, MA 02138, USA), AC(Harvard-Smithsonian Center for Astrophysics, 60 Garden St., Cambridge, MA 02138, USA), AD(Center for Cosmology and Particle Physics, New York University, 4 Washington Place, New York, NY 10003, USA), AE(Steward Observatory, University of Arizona, 933 N.

Our model follows observed mass and luminosity functions of both star-forming and quiescent galaxies, and reproduces the redshift evolution of colors, sizes, star formation, and chemical properties of the observed galaxy population. Unlike other existing approaches, our model includes a self-consistent treatment of stellar and photoionized gas emission and dust attenuation based on the BEAGLE tool. The mock galaxy catalogs generated with our new model can be used to simulate and optimize extragalactic surveys with future facilities such as the James Webb Space Telescope (JWST), and to enable critical assessments of analysis procedures, interpretation tools, and measurement systematics for both photometric and spectroscopic data. As a first application of this work, we make predictions for the upcoming JWST Advanced Deep Extragalactic Survey (JADES), a joint program of the JWST/NIRCam and NIRSpec Guaranteed Time Observations teams. We show that JADES will detect, with NIRCam imaging, 1000s of galaxies at z ≳ 6, and 10s at z ≳ 10 at {m}{AB}≲ 30 (5σ) within the 236 arcmin2 of the survey. The JADES data will enable accurate constraints on the evolution of the UV luminosity function at z > 8, and resolve the current debate about the rate of evolution of galaxies at z ≳ 8. Ready-to-use mock catalogs and software to generate new realizations are publicly available as the JAdes extraGalactic Ultradeep Artificial Realizations (JAGUAR) package. %3 10.3847/1538-4365/aabcbb %= eprint: arXiv:1802.05272 %@ 0067-0049 %0 Electronic Article %T Overview of the DESI Legacy Imaging Surveys %A Dey, Arjun %A Schlegel, David J. %A Lang, Dustin %A Blum, Robert %A Burleigh, Kaylan %A Fan, Xiaohui %A Findlay, Joseph R. %A Finkbeiner, Doug %A Herrera, David %A Juneau, Stephanie %A Landriau, Martin %A Levi, Michael %A McGreer, Ian %A Meisner, Aaron %A Myers, Adam D. %A Moustakas, John %A Nugent, Peter %A Patej, Anna %A Schlafly, Edward F. %A Walker, Alistair R. %A Valdes, Francisco %A Weaver, Benjamin A. %A Zou, Christophe Yeche Hu %A Zhou, Xu %A Abareshi, Behzad %A Abbott, T.

The combined survey footprint is split into two contiguous areas by the Galactic plane. The optical imaging is conducted using a unique strategy of dynamically adjusting the exposure times and pointing selection during observing that results in a survey of nearly uniform depth. In addition to calibrated images, the project is delivering a catalog, constructed by using a probabilistic inference-based approach to estimate source shapes and brightnesses. The catalog includes photometry from the grz optical bands and from four mid-infrared bands (at 3.4, 4.6, 12 and 22 micorons) observed by the Wide-field Infrared Survey Explorer (WISE) satellite during its full operational lifetime. The project plans two public data releases each year. All the software used to generate the catalogs is also released with the data. This paper provides an overview of the Legacy Surveys project. %= eprint: arXiv:1804.08657 %0 Journal Article %T The Fourteenth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the Extended Baryon Oscillation Spectroscopic Survey and from the Second Phase of the Apache Point Observatory Galactic Evolution Experiment %A Abolfathi, Bela %A Aguado, D.

This paper describes the second data release from this phase, and the 14th from SDSS overall (making this Data Release Fourteen or DR14). This release makes the data taken by SDSS-IV in its first two years of operation (2014-2016 July) public. Like all previous SDSS releases, DR14 is cumulative, including the most recent reductions and calibrations of all data taken by SDSS since the first phase began operations in 2000. New in DR14 is the first public release of data from the extended Baryon Oscillation Spectroscopic Survey; the first data from the second phase of the Apache Point Observatory (APO) Galactic Evolution Experiment (APOGEE-2), including stellar parameter estimates from an innovative data-driven machine-learning algorithm known as “The Cannon” and almost twice as many data cubes from the Mapping Nearby Galaxies at APO (MaNGA) survey as were in the previous release (N = 2812 in total). This paper describes the location and format of the publicly available data from the SDSS-IV surveys. We provide references to the important technical papers describing how these data have been taken (both targeting and observation details) and processed for scientific use. The SDSS web site (www.sdss.org) has been updated for this release and provides links to data downloads, as well as tutorials and examples of data use. SDSS-IV is planning to continue to collect astronomical data until 2020 and will be followed by SDSS-V. %3 10.3847/1538-4365/aa9e8a %= eprint: arXiv:1707.09322 %@ 0067-0049 %0 Journal Article %T Constraining the baryon-dark matter relative velocity with the large-scale three-point correlation function of the SDSS BOSS DR12 CMASS galaxies %A Slepian, Zachary %A Eisenstein, Daniel J. %A Blazek, Jonathan A. %A Brownstein, Joel R. %A Chuang, Chia-Hsun %A Gil-Marín, Héctor %A Ho, Shirley %A Kitaura, Francisco-Shu %A McEwen, Joseph E. %A Percival, Will J. %A Ross, Ashley J. %A Rossi, Graziano %A Seo, Hee-Jong %A Slosar, Anže %A Vargas-Magaña, Mariana %+ AA(Harvard-Smithsonian Center for Astrophysics, 60 Garden Street, Cambridge, MA 02138, USA), AB(Harvard-Smithsonian Center for Astrophysics, 60 Garden Street, Cambridge, MA 02138, USA), AC(Center for Cosmology and Astroparticle Physics, Department of Physics, The Ohio State University, OH 43210, USA), AD(Department of Physics and Astronomy, University of Utah, Salt Lake City, UT 84112, USA), AE(Instituto de Física Teórica, (UAM/CSIC), Universidad Autónoma de Madrid, Cantoblanco, E-28049 Madrid, Spain; Leibniz-Institut für Astrophysik Potsdam (AIP), An der Sternwarte 16, D-14482 Potsdam, Germany), AF(Sorbonne Universités, Institut Lagrange de Paris (ILP), 98 bis Boulevard Arago, F-75014 Paris, France; Laboratoire de Physique Nucléaire et de Hautes Energies, Université Pierre et Marie Curie, 4 Place Jussieu, F-75005 Paris, France), AG(Lawrence Berkeley National Lab, 1 Cyclotron Road, Berkeley, CA 94720, USA; McWilliams Center for Cosmology, Department of Physics, Carnegie Mellon University, 5000 Forbes Ave., Pittsburgh, PA 15213, USA; Department of Physics, University of California, Berkeley, CA 94720, USA), AH(Leibniz-Institut für Astrophysik Potsdam (AIP), An der Sternwarte 16, D-14482 Potsdam, Germany), AI(Center for Cosmology and Astroparticle Physics, Department of Physics, The Ohio State University, OH 43210, USA), AJ(Institute of Cosmology and Gravitation, University of Portsmouth, Dennis Sciama Building, Portsmouth PO1 3FX, UK), AK(Center for Cosmology and Astroparticle Physics, Department of Physics, The Ohio State University, OH 43210, USA), AL(Department of Physics and Astronomy, Sejong University, Seoul 143-747, Korea), AM(Department of Physics and Astronomy, Ohio University, Clippinger Labs, Athens, OH 45701, USA), AN(Brookhaven National Laboratory, Upton, NY 11973, USA), AO(Instituto de Física, Universidad Nacional Autónoma de México, Apdo.

We find no detected signal and place the constraint bv < 0.01 on the relative velocity bias for the CMASS galaxies. This bias is an important potential systematic of baryon acoustic oscillation (BAO) method measurements of the cosmic distance scale using the two-point clustering. Our limit on the relative velocity bias indicates a systematic shift of no more than 0.3 per cent rms in the distance scale inferred from the BAO feature in the BOSS two-point clustering, well below the 1 per cent statistical error of this measurement. This constraint is the most stringent currently available and has important implications for the ability of upcoming large-scale structure surveys such as the Dark Energy Spectroscopic Instrument (DESI) to self-protect against the relative velocity as a possible systematic. %3 10.1093/mnras/stx2723 %@ 0035-8711 %0 Journal Article %T The clustering of the SDSS-IV extended Baryon Oscillation Spectroscopic Survey DR14 quasar sample: first measurement of baryon acoustic oscillations between redshift 0.8 and 2.2 %A Ata, Metin %A Baumgarten, Falk %A Bautista, Julian %A Beutler, Florian %A Bizyaev, Dmitry %A Blanton, Michael R. %A Blazek, Jonathan A. %A Bolton, Adam S. %A Brinkmann, Jonathan %A Brownstein, Joel R. %A Burtin, Etienne %A Chuang, Chia-Hsun %A Comparat, Johan %A Dawson, Kyle S. %A de la Macorra, Axel %A Du, Wei %A du Mas des Bourboux, Hélion %A Eisenstein, Daniel J. %A Gil-Marín, Héctor %A Grabowski, Katie %A Guy, Julien %A Hand, Nick %A Ho, Shirley %A Hutchinson, Timothy A. %A Ivanov, Mikhail M. %A Kitaura, Francisco-Shu %A Kneib, Jean-Paul %A Laurent, Pierre %A Le Goff, Jean-Marc %A McEwen, Joseph E. %A Mueller, Eva-Maria %A Myers, Adam D. %A Newman, Jeffrey A. %A Palanque-Delabrouille, Nathalie %A Pan, Kaike %A Pâris, Isabelle %A Pellejero-Ibanez, Marcos %A Percival, Will J. %A Petitjean, Patrick %A Prada, Francisco %A Prakash, Abhishek %A Rodríguez-Torres, Sergio A. %A Ross, Ashley J. %A Rossi, Graziano %A Ruggeri, Rossana %A Sánchez, Ariel G. %A Satpathy, Siddharth %A Schlegel, David J. %A Schneider, Donald P. %A Seo, Hee-Jong %A Slosar, Anže %A Streblyanska, Alina %A Tinker, Jeremy L. %A Tojeiro, Rita %A Vargas Magaña, Mariana %A Vivek, M. %A Wang, Yuting %A Yèche, Christophe %A Yu, Liang %A Zarrouk, Pauline %A Zhao, Cheng %A Zhao, Gong-Bo %A Zhu, Fangzhou %+ AA(Leibniz-Institut für Astrophysik Potsdam (AIP), An der Sternwarte 16, D-14482 Potsdam, Germany), AB(Leibniz-Institut für Astrophysik Potsdam (AIP), An der Sternwarte 16, D-14482 Potsdam, Germany; Humboldt-Universität zu Berlin, Institut für Physik, Newtonstrasse 15, D-12589, Berlin, Germany), AC(Department Physics and Astronomy, University of Utah, 115 S 1400 E, Salt Lake City, UT 84112, USA), AD(Institute of Cosmology & Gravitation, Dennis Sciama Building, University of Portsmouth, Portsmouth, PO1 3FX, UK 0000-0003-0467-5438), AE(Apache Point Observatory and New Mexico State University, PO Box 59, Sunspot, NM 88349, USA; Sternberg Astronomical Institute, Moscow State University, Universitetski pr. 13, 119992, Moscow, Russia), AF(Center for Cosmology and Particle Physics, Department of Physics, New York University, New York, NY 10003, USA), AG(Institute of Physics, Laboratory of Astrophysics, École Polytechnique Fédérale de Lausanne (EPFL), Observatoire de Sauverny, 1290 Versoix, Switzerland), AH(Department Physics and Astronomy, University of Utah, 115 S 1400 E, Salt Lake City, UT 84112, USA; National Optical Astronomy Observatory, 950 N Cherry Ave, Tucson, AZ 85719, USA), AI(Apache Point Observatory and New Mexico State University, PO Box 59, Sunspot, NM 88349, USA), AJ(Department Physics and Astronomy, University of Utah, 115 S 1400 E, Salt Lake City, UT 84112, USA), AK(IRFU,CEA, Université Paris-Saclay, F-91191 Gif-sur-Yvette, France), AL(Leibniz-Institut für Astrophysik Potsdam (AIP), An der Sternwarte 16, D-14482 Potsdam, Germany), AM(Max-Planck-Institut für Extraterrestrische Physik, Postfach 1312, Giessenbachstr., 85748 Garching bei München, Germany), AN(Department Physics and Astronomy, University of Utah, 115 S 1400 E, Salt Lake City, UT 84112, USA), AO(Instituto de Física, Universidad Nacional Autónoma de México, Apdo.

We consider a sample of 147 000 quasars from the extended Baryon Oscillation Spectroscopic Survey (eBOSS) distributed over 2044 square degrees with redshifts 0.8 < z < 2.2 and measure their spherically averaged clustering in both configuration and Fourier space. Our observational data set and the 1400 simulated realizations of the data set allow us to detect a preference for BAO that is greater than 2.8σ. We determine the spherically averaged BAO distance to z = 1.52 to 3.8 per cent precision: DV(z = 1.52) = 3843 ± 147(rd/rd, fid)Mpc. This is the first time the location of the BAO feature has been measured between redshifts 1 and 2. Our result is fully consistent with the prediction obtained by extrapolating the Planck flat ΛCDM best-fitting cosmology. All of our results are consistent with basic large-scale structure (LSS) theory, confirming quasars to be a reliable tracer of LSS, and provide a starting point for numerous cosmological tests to be performed with eBOSS quasar samples. We combine our result with previous, independent, BAO distance measurements to construct an updated BAO distance-ladder. Using these BAO data alone and marginalizing over the length of the standard ruler, we find ΩΛ > 0 at 6.6σ significance when testing a ΛCDM model with free curvature. %3 10.1093/mnras/stx2630 %= eprint: arXiv:1705.06373 %@ 0035-8711 %0 Conference Paper %T Redshift Evolution of Non-Gaussianity in Cosmic Large-Scale Structure %A Sullivan, James %A Wiegand, Alexander %A Eisenstein, Daniel %+ AA(Harvard-Smithsonian Center for Astrophysics), AB(Harvard-Smithsonian Center for Astrophysics), AC(Harvard-Smithsonian Center for Astrophysics) %B American Astronomical Society Meeting Abstracts #231 %V 231 %D 2018 %8 January 1, 2018 %U http://adsabs.harvard.edu/abs/2018AAS...23135101S %X We probe the higher-order galaxy clustering in the final data release (DR12) of the Sloan Digital Sky Survey using germ-grain Minkowski Functionals (MFs). Our data selection contains 979,430 BOSS galaxies from both the northern and southern galactic caps over the redshift range 0.2 - 0.6. We extract the higher-order parts of the MFs and find deviations from the case without higher order MFs with chi-squared values of order 1000 for 24 degrees of freedom across the entire data selection. We show the MFs to be sensitive to contributions up to the five-point correlation function across the entire data selection. We measure significant redshift evolution in the higher-order functionals for the first time, with a percentage growth between redshift bins of approximately 20 % in both galactic caps. This is a nearly a factor of 2 greater than similar growth in the two-point correlation function and will allow for tests of non-linear structure growth by comparing the three-point and higher-order parts to their expected theoretical values.
