The Power of DESI for Photometric Redshift Calibration: A Case Study with KiDS-1000
Diana Blanco, Alexie Leauthaud, Johannes Ulf Lange +64
Accurate redshift estimates are a critical requirement for weak lensing surveys and one of the main uncertainties in constraints on dark energy and large-scale cosmic structure. In…
Cosmological Constraints from Full-Scale Clustering and Galaxy-Galaxy Lensing with DESI DR1
Johannes U. Lange, Alexandra Wells, Andrew Hearin +76
We present constraints on cosmic structure growth from the analysis of galaxy clustering and galaxy--galaxy lensing with galaxies from the Dark Energy Spectroscopic Instrument (DES…
The Composite Spectrum of QSO Absorption Line Systems in DESI DR2
Lucas Napolitano, Adam D. Myers, Adam Tedeschi +43
We present details regarding a composite spectrum of quasar (QSO) absorption line systems. In this composite spectrum we identify more than 70 absorption lines, and observe oxygen…
Baryon fraction from the BAO amplitude: a consistent approach to parameterizing perturbation growth
Andrea Crespi, Will J. Percival, Alex Krolewski +51
Galaxy clustering constrains the baryon fraction Omega_b/Omega_m through the amplitude of baryon acoustic oscillations and the suppression of perturbations entering the horizon bef…
Effect of local environment on Ly line profile in DESI/ODIN LAEs
Ana Sofía M. Uzsoy, Arjun Dey, Anand Raichoor +51
Lyman-Alpha Emitters (LAEs) are star-forming galaxies with significant Ly emission and are often used as tracers of large-scale structure at high redshift. We explore the relati…
The Multi-Phase Circumgalactic Medium of DESI Emission-Line Galaxies at z~1.5
Ting-Wen Lan, J. Xavier Prochaska, J. Aguilar +39
We study the multi-phase circumgalactic medium (CGM) of emission line galaxies (ELGs) at , traced by MgII, and CIV, …
Quasars acting as Strong Lenses Found in DESI DR1
Everett McArthur, Martin Millon, Meredith Powell +52
Quasars acting as strong gravitational lenses offer a rare opportunity to probe the redshift evolution of scaling relations between supermassive black holes and their host galaxies…
DESI DR2 Galaxy Luminosity Functions
Samuel G. Moore, Shaun Cole, Michael Wilson +54
We present galaxy luminosity functions (LFs) for the Dark Energy Spectroscopic Instrument (DESI) DR2 Bright Galaxy Survey (BGS) in the g,r,z, and w1 bands over 0.002<z<0.6. Our ana…
Dwarf galaxy halo masses from spectroscopic and photometric lensing in DESI and DES
Helena Treiber, Alexandra Amon, Risa H. Wechsler +46
We present the most precise and lowest-mass weak lensing measurements of dwarf galaxies to date, enabled by spectroscopic lenses from the Dark Energy Spectroscopic Instrument (DESI…
Without the Sound Horizon (or Supernovae): A 2% Measurement in DESI DR1
E. A. Zaborowski, P. Taylor, K. Honscheid +58
The sound horizon scale is a key source of information for early-time measurements, and is therefore a common target of new physics proposed to solve the Hubble tension…
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…
DESI DR1 Ly forest: 3D full-shape analysis and cosmological constraints
Andrei Cuceu, Hiram K. Herrera-Alcantar, Calum Gordon +75
We perform an analysis of the full shapes of Lyman- (Ly) forest correlation functions measured from the first data release (DR1) of the Dark Energy Spectroscopic Instrument (…
Clustering analysis of medium-band selected high-redshift galaxies
H. Ebina, M. White, A. Raichoor +57
Next-generation large-scale structure spectroscopic surveys will probe cosmology at high redshifts , relying on abundant galaxy tracers such as Ly emitters (LAE…
Probing the limits of cosmological information from the Lyman- forest 2-point correlation functions
Wynne Turner, Andrei Cuceu, Paul Martini +48
The standard cosmological analysis with the Ly forest relies on a continuum fitting procedure that suppresses information on large scales and distorts the three-dimensional corr…
Clustering of DESI galaxies split by thermal Sunyaev-Zeldovich effect
M. Rashkovetskyi, D. J. Eisenstein, J. Aguilar +46
The thermal Sunyaev-Zeldovich (tSZ) effect is associated with galaxy clusters - extremely large and dense structures tracing the dark matter with a higher bias than isolated galaxi…
The Lyman- Forest from LBGs: First 3D Correlation Measurement with DESI and Prospects for Cosmology
