Direct Measurement of Galaxy Assembly Bias using DESI DR1 Data
Zhiwei Shao, Ying Zu, Andrés N. Salcedo +54
We report the first direct measurement of galaxy assembly bias, a critical systematic in cosmology, from the Dark Energy Spectroscopic Instrument (DESI) Bright Galaxy Survey. We in…
Robust Measurement of Stellar Streams Around the Milky Way: Correcting Spatially Variable Observational Selection Effects in Optical Imaging Surveys
K. K. Boone, P. S. Ferguson, M. Tabbutt +47
Observations of density variations in stellar streams are a promising probe of low-mass dark matter substructure in the Milky Way. However, survey systematics such as variations in…
A New Way to Discover Strong Gravitational Lenses: Pair-wise Spectroscopic Search from DESI DR1
Yuan-Ming Hsu, Xiaosheng Huang, Christopher J. Storfer +47
We present a new method to search for strong gravitational lensing systems by pairing spectra that are close together on the sky in a spectroscopic survey. We visually inspect 26,6…
The mass of the Milky Way from outer halo stars measured by DESI DR1
Gustavo E. Medina, Ting S. Li, Gwendolyn M. Eadie +50
As a benchmark for galaxy evolution and dark matter studies, the total mass of the Milky Way is a parameter of cosmological significance, and its value at large radii from the Gala…
DESI EDR: Calibrating the Tully-Fisher Relationship with the DESI Peculiar Velocity Survey
K. Douglass, S. BenZvi, N. Uberoi +45
We calibrate the Tully-Fisher relation (TFR) with data from the DESI Peculiar Velocity (PV) Survey taken during the Survey Validation (SV) period of the DESI galaxy redshift survey…
DESI DR2 reference mocks: clustering results from Uchuu-BGS and LRG
E. Fernández-García, F. Prada, A. Smith +64
The aim of this work is to construct mock galaxy catalogues that accurately reproduce the redshift evolution of galaxy number density, clustering statistics, and baryonic propertie…
Beyond Traditional Diagnostics: Identifying Active Galactic Nuclei with Spectral Energy Distribution Fitting in DESI Data
M. Siudek, M. Mezcua, C. Circosta +36
Active galactic nuclei (AGN) are typically identified through their distinctive X-ray or radio emissions, mid-infrared (MIR) colors, or emission lines. However, each method capture…
ODIN: The LAE Lyα Luminosity Function over Cosmic Time and Environmental Density
Gautam Nagaraj, Robin Ciardullo, Caryl Gronwall +53
The ubiquity and relative ease of discovery make Ly emitting galaxies (LAEs) ideal tracers for cosmology. In addition, because Ly is a resonance line,…
DESI Emission-line Galaxies: Clustering Dependence on Stellar Mass and [OII] Luminosity
T. Hagen, K. S. Dawson, Z. Zheng +49
We measure the projected two-point correlation functions of emission-line galaxies (ELGs) from the Dark Energy Spectroscopic Instrument (DESI) One-Percent Survey and model their de…
DESI Data Release 1: Stellar Catalogue
Sergey E. Koposov, Ting S. Li, C. Allende Prieto +65
In this paper we present the stellar Value-Added Catalogue (VAC) based on the DESI Data Release 1. This VAC contains stellar parameter, abundance and radial velocity measurements f…
Backlighting extended gas halos around luminous red galaxies: kinematic Sunyaev-Zel'dovich effect from DESI Y1 x ACT
Bernardita Ried Guachalla, Emmanuel Schaan, Boryana Hadzhiyska +58
The gas density profile around galaxies, shaped by feedback and affecting the galaxy lensing signal, is imprinted on the cosmic microwave background (CMB) by the kinematic Sunyaev-…
A Comprehensive Characterization of Galaxy-cool CGM Connections at with DESI Year 1 Data
Yu Voon Ng, Ting-Wen Lan, J. Xavier Prochaska +41
We investigate the relationships between the cool circumgalactic medium (CGM), traced by Ca II absorption lines, and galaxy properties at using galaxy-quasa…
PAC in DESI. I. Galaxy Stellar Mass Function into the Frontier
Kun Xu, Y. P. Jing, Shaun Cole +34
The Photometric Objects Around Cosmic Webs (PAC) method integrates cosmological photometric and spectroscopic surveys, offering valuable insights into galaxy formation. PAC measure…
