Constraining the phase shift of relativistic species in DESI BAOs
Abbé M. Whitford, Hugo Rivera-Morales, Cullan Howlett +36
In the early Universe, neutrinos decouple quickly from the primordial plasma and propagate without further interactions. The impact of free-streaming neutrinos is to create a tempo…
DESIVAST: A Catalog of Low-Redshift Voids using Data from the DESI DR1 Bright Galaxy Survey
Hernan Rincon, Segev BenZvi, Kelly Douglass +37
We present three separate void catalogs created using a volume-limited sample of the DESI Year 1 Bright Galaxy Survey. We use the algorithms VoidFinder and V2 to construct void cat…
The Atacama Cosmology Telescope DR6 and DESI: Structure growth measurements from the cross-correlation of DESI Legacy Imaging galaxies and CMB lensing from ACT DR6 and Planck PR4
Frank J. Qu, Qianjun Hang, Gerrit Farren +51
We measure the growth of cosmic density fluctuations on large scales and across the redshift range through the cross-correlation of the ACT DR6 CMB lensing map and gala…
Selection of high-redshift Lyman-Break Galaxies from broadband and wide photometric surveys
C. Payerne, W. d'Assignies Doumerg, C. Yèche +44
In this paper, we investigate the possibility of selecting high-redshift Lyman-Break Galaxies (LBG) using current and future broadband wide photometric surveys, such as UNIONS or t…
Detection of the large-scale tidal field with galaxy multiplet alignment in the DESI Y1 spectroscopic survey
Claire Lamman, Daniel Eisenstein, Jaime E. Forero-Romero +36
We explore correlations between the orientations of small galaxy groups, or "multiplets", and the large-scale gravitational tidal field. Using data from the Dark Energy Spectroscop…
Measuring using DESI Legacy Imaging Surveys Emission-Line Galaxies and Planck CMB Lensing and the Impact of Dust on Parameter Inference
Tanveer Karim, Sukhdeep Singh, Mehdi Rezaie +39
Measuring the growth of structure is a powerful probe for studying the dark sector, especially in light of the tension between primary CMB anisotropy and low-redshift surveys…
Constraints on the spacetime variation of the fine-structure constant using DESI emission-line galaxies
Linhua Jiang, Zhiwei Pan, Jessica Nicole Aguilar +38
We present strong constraints on the spacetime variation of the fine-structure constant using the Dark Energy Spectroscopic Instrument (DESI). In this pilot work, we utilize $\…
High redshift LBGs from deep broadband imaging for future spectroscopic surveys
Vanina Ruhlmann-Kleider, Christophe Yèche, Christophe Magneville +60
Lyman break galaxies (LBGs) are promising probes for clustering measurements at high redshift, , a region only covered so far by Lyman- forest measurements. In this paper,…
Redshift evolution and covariances for joint lensing and clustering studies with DESI Y1
Sihan Yuan, Chris Blake, Alex Krolewski +48
Galaxy-galaxy lensing (GGL) and clustering measurements from the Dark Energy Spectroscopic Instrument Year 1 (DESI Y1) dataset promise to yield unprecedented combined-probe tests o…
Synthetic spectra for Lyman- forest analysis in the Dark Energy Spectroscopic Instrument
Hiram K. Herrera-Alcantar, Andrea Muñoz-Gutiérrez, Ting Tan +51
Synthetic data sets are used in cosmology to test analysis procedures, to verify that systematic errors are well understood and to demonstrate that measurements are unbiased. In th…
