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…

Constraints on dark matter to dark radiation conversion in the late universe with DES-Y1 and external data

Angela Chen, Dragan Huterer, Sujeong Lee +81

We study a phenomenological class of models where dark matter converts to dark radiation in the low redshift epoch. This class of models, dubbed DMDR, characterizes the evolution o…
