DESI DR2 Results IV: Alcock-Paczyński Measurements from the Lyman Alpha Forest and Cosmological Constraints
DESI Collaboration, A. G. Adame, J. Aguilar +164
The DESI DR2 analysis measures the Alcock‑Paczynski effect using the full shape of Lyman‑α forest auto‑ and cross‑correlations, achieving 1% precision at redshift 2.33 and providin…
Cosmological analysis of the DESI DR1 Lyman alpha 1D power spectrum
J. Chaves-Montero, A. Font-Ribera, P. McDonald +63
We present the cosmological analysis of the one-dimensional Lyman- flux power spectrum from the first data release of the Dark Energy Spectroscopic Instrument (DESI). We captur…
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…
DESI DR1 Ly 1D power spectrum: Validation of estimators
N. G. Karaçaylı, C. Ravoux, P. Martini +53
The Data Release 1 (DR1) of the Dark Energy Spectroscopic Instrument (DESI) is the largest sample to date for small-scale Ly forest cosmology, accessed through its one-dimensio…
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…
DESI DR1 Lyα 1D power spectrum: The Fast Fourier Transform estimator measurement
Corentin Ravoux, Marie-Lynn Abdul-Karim, Jean-Marc Le Goff +64
We present the one-dimensional Lyman- forest power spectrum measurement derived from the data release 1 (DR1) of the Dark Energy Spectroscopic Instrument (DESI). The measuremen…
