Unraveling emission line galaxy conformity at z~1 with DESI early data
Sihan Yuan, Risa H. Wechsler, Yunchong Wang +32
Emission line galaxies (ELGs) are now the preeminent tracers of large-scale structure at z>0.8 due to their high density and strong emission lines, which enable accurate redshift m…
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…
The DESI One-Percent Survey: Modelling the clustering and halo occupation of all four DESI tracers with Uchuu
F. Prada, J. Ereza, A. Smith +44
We present results from a set of mock lightcones for the DESI One-Percent Survey, created from the Uchuu simulation. This This 8 (Gpc/h)^3 N-body simulation comprises 2.1 trillion…
The DESI One-Percent Survey: Exploring A Generalized SHAM for Multiple Tracers with the UNIT Simulation
Jiaxi Yu, Cheng Zhao, Violeta Gonzalez-Perez +40
We perform SubHalo Abundance Matching (SHAM) studies on UNIT simulations with \{\}-SHAM and \{\}-SHAM. They are designe…
Synthetic light cone catalogues of modern redshift and weak lensing surveys with AbacusSummit
Boryana Hadzhiyska, Sihan Yuan, Chris Blake +32
The joint analysis of different cosmological probes, such as galaxy clustering and weak lensing, can potentially yield invaluable insights into the nature of the primordial Univers…
2D k-th nearest neighbor statistics: a highly informative probe of galaxy clustering
Sihan Yuan, Alvaro Zamora, Tom Abel
Beyond standard summary statistics are necessary to summarize the rich information on non-linear scales in the era of precision galaxy clustering measurements. For the first time,…
First Detection of the BAO Signal from Early DESI Data
Jeongin Moon, David Valcin, Michael Rashkovetskyi +65
We present the first detection of the baryon acoustic oscillations (BAO) signal obtained using unblinded data collected during the initial two months of operations of the Stage-IV…
