Alleviating prior dependencies for DESI DR1 clustering fits through reparameterization

Marco Bonici, Simone Paradiso, Glenn McGee +48

Bayesian analyses of the full-shape clustering of Dark Energy Spectroscopic Instrument (DESI) Data Release 1 (DR1) exhibit prior-volume projection effects, whereby weakly constrain…

Cosmological Constraints from Full-Scale Clustering and Galaxy-Galaxy Lensing with DESI DR1

Johannes U. Lange, Alexandra Wells, Andrew Hearin +76

We present constraints on cosmic structure growth from the analysis of galaxy clustering and galaxy-galaxy lensing with galaxies from the Dark Energy Spectroscopic Instrument (DESI…

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…

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…
