Measuring the conditional luminosity and stellar mass functions of galaxies by combining the DESI LS DR9, SV3 and Y1 data
Yirong Wang, Xiaohu Yang, Yizhou Gu +42
In this investigation, we leverage the combination of Dark Energy Spectroscopic Instrument Legacy imaging Surveys Data Release 9 (DESI LS DR9), Survey Validation 3 (SV3), and Year…
Generating mock galaxy catalogues for flux-limited samples like the DESI Bright Galaxy Survey
A. Smith, C. Grove, S. Cole +28
Accurate mock galaxy catalogues are crucial to validate analysis pipelines used to constrain dark energy models. We present a fast HOD-fitting method which we apply to the AbacusSu…
A Spectroscopic Search for Optical Emission Lines from Dark Matter Decay
Hanyue Wang, Daniel J. Eisenstein, Jessica Nicole Aguilar +19
We search for narrow-line optical emission from dark matter decay by stacking dark-sky spectra from the Dark Energy Spectroscopic Instrument (DESI) at the redshift of nearby galaxi…
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…
The DESI One-Percent Survey: Evidence for Assembly Bias from Low-Redshift Counts-in-Cylinders Measurements
Alan N. Pearl, Andrew R. Zentner, Jeffrey A. Newman +28
We explore the galaxy-halo connection information that is available in low-redshift samples from the early data release of the Dark Energy Spectroscopic Instrument (DESI). We model…
DESI luminous red galaxy samples for cross-correlations
Rongpu Zhou, Simone Ferraro, Martin White +36
We present two galaxy samples, selected from DESI Legacy Imaging Surveys (LS) DR9, with approximately 20,000 square degrees of coverage and spectroscopic redshift distributions des…
The DESI One-Percent Survey: A concise model for galactic conformity of ELGs
Hongyu Gao, Y. P. Jing, Kun Xu +27
Galactic conformity is the phenomenon in which a galaxy of a certain physical property is correlated with its neighbors of the same property, implying a possible causal relationshi…
Mitigating the noise of DESI mocks using analytic control variates
Boryana Hadzhiyska, Martin J. White, Xinyi Chen +30
In order to address fundamental questions related to the expansion history of the Universe and its primordial nature with the next generation of galaxy experiments, we need to mode…
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…
The DESI One-Percent survey: constructing galaxy-halo connections for ELGs and LRGs using auto and cross correlations
Hongyu Gao, Y. P. Jing, Shanquan Gui +31
In the current Dark Energy Spectroscopic Instrument (DESI) survey, emission line galaxies (ELGs) and luminous red galaxies (LRGs) are essential for mapping the dark matter distribu…
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…
Changing-look Active Galactic Nuclei from the Dark Energy Spectroscopic Instrument. I.Sample from the Early Data
Wei-Jian Guo, Hu Zou, Victoria Anne Fawcett +34
Changing-look Active Galactic Nuclei (CL AGN) can be generally confirmed by the emergence (turn-on) or disappearance (turn-off) of broad emission lines, associated with a transient…
Long-term follow-up observations of extreme coronal line emitting galaxies
Peter Clark, Or Graur, Joseph Callow +40
We present new spectroscopic and photometric follow-up observations of the known sample of extreme coronal line emitting galaxies (ECLEs) identified in the Sloan Digital Sky Survey…
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…
