Kavli Affiliate: Risa H. Wechsler | First 5 Authors: ChangHoon Hahn, Jessica Nicole Aguilar, Shadab Alam, Steven Ahlen, David Brooks | Summary: 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 of DESI’s survey validation programs conducted […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Sihan Yuan, Hanyu Zhang, Ashley J. Ross, Jamie Donald-McCann, Boryana Hadzhiyska | Summary: We present the first comprehensive Halo Occupation Distribution (HOD) analysis of the DESI One-Percent survey Luminous Red Galaxy (LRG) and Quasi-Stellar Object (QSO) samples. We constrain the HOD of each sample and test […]

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Sal Wanying Fu, Daniel R. Weisz, Else Starkenburg, Nicolas Martin, Alessandro Savino | Summary: We present uniformly measured stellar metallicities for 463 stars in 13 Milky Way (MW) ultra-faint dwarf galaxies (UFDs; $M_V = -7.1$ to $-0.8$) using narrowband CaHK (F395N) imaging taken with the Hubble […]
Kavli Affiliate: Luis Ho | Summary:Bulge-disk (B-D) decomposition is an effective diagnostic to characterize the galaxy morphology and understand its evolution across time. So far, high-quality data have allowed detailed B-D decomposition to redshift below 0.5, with limited excursions over small volumes at higher redshifts. Next-generation large sky space surveys in optical, e.g. from the […]
