Validation of semi-analytical, semi-empirical covariance matrices for two-point correlation function for Early DESI data

Michael Rashkovetskyi, Daniel J. Eisenstein, Jessica Nicole Aguilar +34

We present an extended validation of semi-analytical, semi-empirical covariance matrices for the two-point correlation function (2PCF) on simulated catalogs representative of Lumin…

DESI Mock Challenge: Constructing DESI galaxy catalogues based on FastPM simulations

Andrei Variu, Shadab Alam, Cheng Zhao +30

Together with larger spectroscopic surveys such as the Dark Energy Spectroscopic Instrument (DESI), the precision of large scale structure studies and thus the constraints on the c…

Local primordial non-Gaussianity from the large-scale clustering of photometric DESI luminous red galaxies

Mehdi Rezaie, Ashley J. Ross, Hee-Jong Seo +46

We use angular clustering of luminous red galaxies from the Dark Energy Spectroscopic Instrument (DESI) imaging surveys to constrain the local primordial non-Gaussianity parameter…

PROVABGS: The Probabilistic Stellar Mass Function of the BGS One-Percent Survey

ChangHoon Hahn, Jessica Nicole Aguilar, Shadab Alam +33

We present the probabilistic stellar mass function (pSMF) of galaxies in the DESI Bright Galaxy Survey (BGS), observed during the One-Percent Survey. The One-Percent Survey was one…

The 2-point correlation function covariance with fewer mocks

Svyatoslav Trusov, Pauline Zarrouk, Shaun Cole +18

We present an approach for accurate estimation of the covariance of 2-point correlation functions that requires fewer mocks than the standard mock-based covariance. This can be ach…

GTC Follow-up Observations of Very Metal-Poor Star Candidates from DESI

Carlos Allende Prieto, David S. Aguado, Jonay I. González Hernández +48

The observations from the Dark Energy Spectroscopic Instrument (DESI) will significantly increase the numbers of known extremely metal-poor stars by a factor of ~ 10, improving the…
