Exploring non-Poisson satellite occupation in HOD models and its impact on 2- and 3-point galaxy clustering
Antoine Rocher
Understanding the connection between galaxies and dark matter halos is a central challenge in modern cosmology. The Halo Occupation Distribution (HOD) framework provides a widely u…
4MOST Cosmology Redshift Survey (CRS): Clustering Properties of CRS Bright Galaxy and Luminous Red Galaxy Target Catalogues
Behnood Bandi, Antoine Rocher, Aurélien Verdier +6
The 4-metre Multi-Object Spectroscopic Telescope Cosmology Redshift Survey (4MOST CRS) will obtain 5.4 million spectroscopic redshifts over ~5700 deg^2 to map large-scale structure…
MUltiplexed Survey Telescope (MUST) Science White Paper I: Overview of Large-Scale Structure Cosmology in the Era of Stage-V Spectroscopic Surveys
Cheng Zhao, Song Huang, Mengfan He +41
The MUltiplexed Survey Telescope (MUST) is a 6.5-meter telescope under development. Dedicated to highly-multiplexed, wide-field spectroscopic surveys, MUST observes over 20,000 tar…
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…
The 4MOST-Cosmology Redshift Survey: Target Selection of Bright Galaxies and Luminous Red Galaxies
Aurelien Verdier, Antoine Rocher, Behnood Bandi +7
The Cosmology Redshift Survey of the 4-metre Multi-Object Spectroscopic Telescope (4MOST-CRS) will provide redshift measurements of galaxies and quasars over 5700{\degsq} in the so…
Enhancing DESI DR1 Full-Shape analyses using HOD-informed priors
Hanyu Zhang, Marco Bonici, Antoine Rocher +57
We present an analysis of DESI Data Release 1 (DR1) that incorporates Halo Occupation Distribution (HOD)-informed priors into Full-Shape (FS) modeling of the power spectrum based o…
