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 deliver…
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…
Frequentist Cosmological Constraints from Full-Shape Clustering Measurements in DESI DR1
James Morawetz, Hanyu Zhang, Marco Bonici +56
We present a frequentist analysis of clustering measurements from Data Release 1 of the Dark Energy Spectroscopic Instrument (DESI) using the standard profile likelihood method. Wh…
