DESI 2024 VI: Cosmological Constraints from the Measurements of Baryon Acoustic Oscillations

We present cosmological results from the measurement of baryon acoustic oscillations (BAO) in galaxy, quasar and Lyman-\(\alpha\) forest tracers from the first year of observations from the Dark Energy Spectroscopic Instrument (DESI), to be released in the DESI Data Release 1. DESI BAO provide robus...

Zusammenfassung:	We present cosmological results from the measurement of baryon acoustic oscillations (BAO) in galaxy, quasar and Lyman-\(\alpha\) forest tracers from the first year of observations from the Dark Energy Spectroscopic Instrument (DESI), to be released in the DESI Data Release 1. DESI BAO provide robust measurements of the transverse comoving distance and Hubble rate, or their combination, relative to the sound horizon, in seven redshift bins from over 6 million extragalactic objects in the redshift range \(0.10.059)\) eV prior. These neutrino-mass constraints are substantially relaxed in models beyond \(\Lambda\)CDM. [Abridged.]
