DESI 2024 VII: Cosmological Constraints from the Full-Shape Modeling of Clustering Measurements

DESI Collaboration, A. G. Adame, J. Aguilar +210

We present cosmological results from the measurement of clustering of galaxy, quasar and Lyman- forest tracers from the first year of observations with the Dark Energy Spectrosc…

DESI 2024 II: Sample Definitions, Characteristics, and Two-point Clustering Statistics

DESI Collaboration, A. G. Adame, J. Aguilar +200

We present the samples of galaxies and quasars used for DESI 2024 cosmological analyses, drawn from the DESI Data Release 1 (DR1). We describe the construction of large-scale struc…

Measuring the Mean Free Path of HI Ionizing Photons at with DESI Y1 Quasars

Anning Gao, Jason X. Prochaska, Zheng Cai +31

The mean free path of ionizing photons () in the intergalactic medium (IGM) is a crucial quantity in modelling the ionization state of IGM and the extragalact…

Analytical and EZmock covariance validation for the DESI 2024 results

Daniel Forero-Sánchez, Michael Rashkovetskyi, Otávio Alves +44

The estimation of uncertainties in cosmological parameters is an important challenge in Large-Scale-Structure (LSS) analyses. For standard analyses such as Baryon Acoustic Oscillat…

DESI 2024 V: Full-Shape Galaxy Clustering from Galaxies and Quasars

A. G. Adame, J. Aguilar, S. Ahlen +195

We present the measurements and cosmological implications of the galaxy two-point clustering using over 4.7 million unique galaxy and quasar redshifts in the range divi…
