The Impact of Spectroscopic Redshift Errors on Cosmological Measurements
Shengyu He, Jiaxi Yu, Antoine Rocher +5
Spectroscopic redshift errors, including redshift uncertainty and catastrophic failures, can bias cosmological measurements from galaxy redshift surveys at sub-percent level. In th…
DESI 2024 V: Full-Shape Galaxy Clustering from Galaxies and Quasars
A. G. Adame, J. Aguilar, S. Ahlen +195
We present the measurements and cosmological implications of the galaxy two-point clustering using over 4.7 million unique galaxy and quasar redshifts in the range divi…
Modified Gravity Constraints from the Full Shape Modeling of Clustering Measurements from DESI 2024
M. Ishak, J. Pan, R. Calderon +68
We present cosmological constraints on deviations from general relativity (GR) from the first-year of clustering observations from Dark Energy Spectroscopic Instrument (DESI) in co…
DESI DR2 Results II: Measurements of Baryon Acoustic Oscillations and Cosmological Constraints
DESI Collaboration, M. Abdul-Karim, J. Aguilar +184
We present baryon acoustic oscillation (BAO) measurements from more than 14 million galaxies and quasars drawn from the Dark Energy Spectroscopic Instrument (DESI) Data Release 2 (…
Constraints on Neutrino Physics from DESI DR2 BAO and DR1 Full Shape
W. Elbers, A. Aviles, H. E. Noriega +116
The Dark Energy Spectroscopic Instrument (DESI) Collaboration has obtained robust measurements of baryon acoustic oscillations (BAO) in the redshift range, , based o…
Analytical and EZmock covariance validation for the DESI 2024 results
Daniel Forero-Sánchez, Michael Rashkovetskyi, Otávio Alves +44
The estimation of uncertainties in cosmological parameters is an important challenge in Large-Scale-Structure (LSS) analyses. For standard analyses such as Baryon Acoustic Oscillat…
