SUMMARY:Astroseminar - Arnaud de Mattia
CLASS:PUBLIC
DESCRIPTION:\"DESI DR2: Survey Overview\, Cosmological Constraints from BAO
 \, and\nPreparation for Full-Shape Analyses\"\n\nArdaud de Mattia (CEA Sac
 lay) is a member of the Dark Energy\nSpectroscopic Instrument (DESI) coll
 aboration\, where he has worked\nsuccessively on photometric systematics (
 through image simulations)\,\nclustering catalogs and two-point statistics
 \, and cosmological\nparameter inference. Arnaud is deeply involved in pip
 eline development\nfor DESI — from catalog creation to cosmological cons
 traints —\nleveraging GPU computing and automatic differentiation whenev
 er\nrelevant. He is also interested in galaxy field-level inference as a\n
 more comprehensive approach to cosmological analysis.
