Alleviating prior dependencies for DESI DR1 clustering fits through reparameterization
Marco Bonici, Simone Paradiso, Glenn McGee +48
Bayesian analyses of the full-shape clustering of Dark Energy Spectroscopic Instrument (DESI) Data Release 1 (DR1) exhibit prior-volume projection effects, whereby weakly constrain…
What Galaxy Clusters Have to Say About Dynamical Dark Energy and
Andrés N. Salcedo, Eduardo Rozo, Hao-Yi Wu +4
We show that, in flat CDM, low-redshift structure probes -- cluster abundances, 32-point analyses, and full-shape clustering -- are mutually consistent, jointly deliveri…
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…
A measurement of from DESI DR1 using energy densities
Alex Krolewski, Andrea Crespi, Will J. Percival +57
We present a new measurement of the Hubble constant, independent of standard rulers and robust to pre-recombination modifications such as Early Dark Energy (EDE), obtained by calib…
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: 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…
Constraining galaxy-halo connection with high-order statistics
Hanyu Zhang, Lado Samushia, David Brooks +13
We investigate using three-point statistics in constraining the galaxy-halo connection. We show that for some galaxy samples, the constraints on the halo occupation distribution pa…
The DESI -body Simulation Project -- II. Suppressing sample variance with fast simulations
Zhejie Ding, Chia-Hsun Chuang, Yu Yu +19
Dark Energy Spectroscopic Instrument (DESI) will construct a large and precise three-dimensional map of our Universe. The survey effective volume reaches $\sim20\Gpchcube$. It is a…
The DESI -body Simulation Project I: Testing the Robustness of Simulations for the DESI Dark Time Survey
Cameron Grove, Chia-Hsun Chuang, Ningombam Chandrachani Devi +19
Analysis of large galaxy surveys requires confidence in the robustness of numerical simulation methods. The simulations are used to construct mock galaxy catalogs to validate data…
A model independent constraint on the temporal evolution of the speed of light
Dandan Wang, Hanyu Zhang, Jinglan Zheng +2
We present a new, model-independent method to reconstruct the temporal evolution of the speed of light using astronomical observations. After validating our pipeline using m…
Probing dynamics of dark energy with latest observations
Yuecheng Zhang, Hanyu Zhang, Dandan Wang +3
We examine the validity of the CDM model, and probe for the dynamics of dark energy using latest astronomical observations. Using the diagnosis, we find that different k…
Dynamical dark energy in light of the latest observations
Gong-Bo Zhao, Marco Raveri, Levon Pogosian +23
A flat Friedman-Roberson-Walker universe dominated by a cosmological constant () and cold dark matter (CDM) has been the working model preferred by cosmologists since the discov…
The extended Baryon Oscillation Spectroscopic Survey (eBOSS): a cosmological forecast
Gong-Bo Zhao, Yuting Wang, Ashley J. Ross +28
We present a science forecast for the eBOSS survey, part of the SDSS-IV project, which is a spectroscopic survey using multiple tracers of large-scale structure, including luminous…
