Alcock-Paczynski Blinding Scheme for the Ly- Forest Analysis
G. Perez-Sanchez, S. F. Beltran, G. Niz +45
We present and validate a blinding method for the Lyman- (Ly) forest analysis based on a modification of the Alcock-Paczynski test. In order to hide the background expansio…
Cosmological constraints from the DESI DR1 joint power spectrum and bispectrum analysis
S. Novell-Masot, H. Gil-MarÃn, L. Verde +48
We derive cosmological parameter constraints from the Dark Energy Spectroscopic Instrument (DESI) Data Release 1 (DR1) galaxy clustering data, based on a joint full-shape analysis…
The BAO scale -- how standard is the standard ruler?
Francisco Asensio-Rivera, Nils Schöneberg, Héctor Gil-MarÃn +1
Analyses of baryon acoustic oscillations (BAO) commonly employ template-based methods to extract compressed parameters from the clustering of dark-matter tracers, which are then in…
The Age of the Universe with Globular Clusters IV: Multiple Stellar Populations
David Valcin, Raul Jimenez, Carmela Lardo +2
We revisit the determination of the age of the Universe from galactic globular clusters, extending previous analyses by explicitly accounting for the presence of multiple stellar p…
Data Release 1 of the Dark Energy Spectroscopic Instrument
DESI Collaboration, M. Abdul Karim, A. G. Adame +306
In 2021 May the Dark Energy Spectroscopic Instrument (DESI) collaboration began a 5-year spectroscopic redshift survey to produce a detailed map of the evolving three-dimensional s…
Cosmological constraints from a joint DESI DR1 Full-Shape and DR2 BAO
D. Forero-Sánchez, H. Gil-MarÃn, L. Verde +61
We present a cosmological analysis combining full-shape (FS) clustering measurements from the Dark Energy Spectroscopic Instrument (DESI) DR1 with baryon acoustic oscillation (BAO)…
