Generating mock galaxy catalogues for flux-limited samples like the DESI Bright Galaxy Survey
A. Smith, C. Grove, S. Cole +28
Accurate mock galaxy catalogues are crucial to validate analysis pipelines used to constrain dark energy models. We present a fast HOD-fitting method which we apply to the AbacusSu…
Unraveling emission line galaxy conformity at z~1 with DESI early data
Sihan Yuan, Risa H. Wechsler, Yunchong Wang +32
Emission line galaxies (ELGs) are now the preeminent tracers of large-scale structure at z>0.8 due to their high density and strong emission lines, which enable accurate redshift m…
Emergence of the Temperature-Density Relation in the Low-Density Intergalactic Medium
Alexandra Wells, David Robinson, Camille Avestruz +1
We examine the evolution of the phase diagram of the low-density intergalactic medium during the Epoch of Reionization in simulation boxes with varying reionization histories from…
DESI Complete Calibration of the Color-Redshift Relation (DC3R2): Results from early DESI data
J. McCullough, D. Gruen, A. Amon +46
We present initial results from the Dark Energy Spectroscopic Instrument (DESI) Complete Calibration of the Color-Redshift Relation (DC3R2) secondary target survey. Our analysis us…
DESI luminous red galaxy samples for cross-correlations
Rongpu Zhou, Simone Ferraro, Martin White +36
We present two galaxy samples, selected from DESI Legacy Imaging Surveys (LS) DR9, with approximately 20,000 square degrees of coverage and spectroscopic redshift distributions des…
Broad Absorption Line Quasars in the Dark Energy Spectroscopic Instrument Early Data Release
S. Filbert, P. Martini, K. Seebaluck +41
Broad absorption line (BAL) quasars are characterized by gas clouds that absorb flux at the wavelength of common quasar spectral features, although blueshifted by velocities that c…
Mitigating the noise of DESI mocks using analytic control variates
Boryana Hadzhiyska, Martin J. White, Xinyi Chen +30
In order to address fundamental questions related to the expansion history of the Universe and its primordial nature with the next generation of galaxy experiments, we need to mode…
Validation of semi-analytical, semi-empirical covariance matrices for two-point correlation function for Early DESI data
Michael Rashkovetskyi, Daniel J. Eisenstein, Jessica Nicole Aguilar +34
We present an extended validation of semi-analytical, semi-empirical covariance matrices for the two-point correlation function (2PCF) on simulated catalogs representative of Lumin…
DESI Mock Challenge: Constructing DESI galaxy catalogues based on FastPM simulations
Andrei Variu, Shadab Alam, Cheng Zhao +30
Together with larger spectroscopic surveys such as the Dark Energy Spectroscopic Instrument (DESI), the precision of large scale structure studies and thus the constraints on the c…
Local primordial non-Gaussianity from the large-scale clustering of photometric DESI luminous red galaxies
Mehdi Rezaie, Ashley J. Ross, Hee-Jong Seo +46
We use angular clustering of luminous red galaxies from the Dark Energy Spectroscopic Instrument (DESI) imaging surveys to constrain the local primordial non-Gaussianity parameter…
The Dark Energy Spectroscopic Instrument: One-dimensional power spectrum from first Lyman- forest samples with Fast Fourier Transform
Corentin Ravoux, Marie Lynn Abdul-Karim, Eric Armengaud +63
We present the one-dimensional Lyman- forest power spectrum measurement using the first data provided by the Dark Energy Spectroscopic Instrument (DESI). The data sample compris…
The Early Data Release of the Dark Energy Spectroscopic Instrument
DESI Collaboration, A. G. Adame, J. Aguilar +266
The Dark Energy Spectroscopic Instrument (DESI) completed its five-month Survey Validation in May 2021. Spectra of stellar and extragalactic targets from Survey Validation constitu…
Constraining primordial non-Gaussianity from DESI quasar targets and Planck CMB lensing
Alex Krolewski, Will J. Percival, Simone Ferraro +33
We detect the cross-correlation between 2.7 million DESI quasar targets across 14,700 deg (180 quasars deg) and Planck 2018 CMB lensing at 30. We use the cross-…
First test of the consistency relation for the large-scale structure using the anisotropic three-point correlation function of BOSS DR12 galaxies (An explanatory video is available at https://youtu.be/Zi36ooLPhss.)
Naonori S. Sugiyama, Daisuke Yamauchi, Tsutomu Kobayashi +6
We present, for the first time, an observational test of the consistency relation for the large-scale structure (LSS) of the Universe through a joint analysis of the anisotropic tw…
First Detection of the BAO Signal from Early DESI Data
Jeongin Moon, David Valcin, Michael Rashkovetskyi +65
