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 DESI One-Percent Survey: Exploring the Halo Occupation Distribution of Luminous Red Galaxies and Quasi-Stellar Objects with AbacusSummit
Sihan Yuan, Hanyu Zhang, Ashley J. Ross +39
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 c…
Dependence of galactic bars on the tidal density field in the SDSS
Qi'an Deng, Ying Zu, Shadab Alam +1
As a key driver of the secular evolution of disc galaxies, bar formation is potentially linked to the surrounding tidal field. We systematically investigate the dependence of bars…
Renormalization of shell model of turbulence
Mahendra K. Verma, Shadab Alam
Renormalization enables a systematic scale-by-scale analysis of multiscale systems. In this paper, we employ \textit{renormalization group} (RG) to the shell model of turbulence an…
