Frequentist Cosmological Constraints from Full-Shape Clustering Measurements in DESI DR1
James Morawetz, Hanyu Zhang, Marco Bonici +53
We present a frequentist analysis of clustering measurements from Data Release 1 of the Dark Energy Spectroscopic Instrument (DESI) using the standard profile likelihood method. Wh…
Modelling the impact of quasar redshift errors on the full-shape analysis of correlations in the Lyman- forest
Calum Gordon, Andrei Cuceu, Andreu Font-Ribera +45
In preparation for the first cosmological measurements from the full-shape of the Lyman- (Ly) forest from DESI, we must carefully model all relevant systematics that might bi…
Measurements of the Thermal Sunyaev-Zel'dovich Effect with ACT and DESI Luminous Red Galaxies
R. Henry Liu, Simone Ferraro, Emmanuel Schaan +54
Cosmic Microwave Background (CMB) photons scatter off the free-electron gas in galaxies and clusters, allowing us to use the CMB as a backlight to probe the gas in and around low-r…
DESIVAST: A Catalog of Low-Redshift Voids using Data from the DESI DR1 Bright Galaxy Survey
Hernan Rincon, Segev BenZvi, Kelly Douglass +37
We present three separate void catalogs created using a volume-limited sample of the DESI Year 1 Bright Galaxy Survey. We use the algorithms VoidFinder and V2 to construct void cat…
Selection of high-redshift Lyman-Break Galaxies from broadband and wide photometric surveys
C. Payerne, W. d'Assignies Doumerg, C. Yèche +44
In this paper, we investigate the possibility of selecting high-redshift Lyman-Break Galaxies (LBG) using current and future broadband wide photometric surveys, such as UNIONS or t…
Inferring the mass content of galaxy clusters with satellite kinematics and Jeans Anisotropic modeling
Rui Shi, Wenting Wang, Zhaozhou Li +7
Satellite galaxies can be used to indicate the dynamical mass of galaxy groups and clusters. In this study, we apply the axis-symmetric Jeans Anisotropic Multi-Gaussian Expansion J…
The Construction of Large-scale Structure Catalogs for the Dark Energy Spectroscopic Instrument
A. J. Ross, J. Aguilar, S. Ahlen +83
We present the technical details on how large-scale structure (LSS) catalogs are constructed from redshifts measured from spectra observed by the Dark Energy Spectroscopic Instrume…
Forward modeling fluctuations in the DESI LRGs target sample using image simulations
Hui Kong, Ashley J. Ross, Klaus Honscheid +50
We use the forward modeling pipeline, Obiwan, to study the imaging systematics of the Luminous Red Galaxies (LRGs) targeted by the Dark Energy Spectroscopic Instrument (DESI). We u…
Baryon Acoustic Oscillation Theory and Modelling Systematics for the DESI 2024 results
Shi-Fan Chen, Cullan Howlett, Martin White +58
This paper provides a comprehensive overview of how fitting of Baryon Acoustic Oscillations (BAO) is carried out within the upcoming Dark Energy Spectroscopic Instrument's (DESI) 2…
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…
The DESI One-Percent Survey: Evidence for Assembly Bias from Low-Redshift Counts-in-Cylinders Measurements
Alan N. Pearl, Andrew R. Zentner, Jeffrey A. Newman +28
We explore the galaxy-halo connection information that is available in low-redshift samples from the early data release of the Dark Energy Spectroscopic Instrument (DESI). We model…
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…
