The interaction between dark matter and dark energy can be incorporated into field theory
models of dark energy that have proved successful in alleviating the coincidence problem …

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 …

The Dark Energy Spectroscopic Instrument (DESI) completed its 5 month Survey Validation
in 2021 May. Spectra of stellar and extragalactic targets from Survey Validation constitute …

Over the next 5 yr, the Dark Energy Spectroscopic Instrument (DESI) will use 10
spectrographs with 5000 fibers on the 4 m Mayall Telescope at Kitt Peak National …

Studies of the geometry and energy content of the Universe, physics of cosmic expansion,
fundamental properties of standard model particles, and growth of structure remain the key …

We present the measurement of Baryon Acoustic Oscillations (BAO) from the Lyman-$\alpha
$(Ly $\alpha $) forest of high-redshift quasars with the first-year dataset of the Dark Energy …

Millions of quasar spectra will be collected by the Dark Energy Spectroscopic Instrument
(DESI), leading to a fourfold increase in the number of known quasars. High-accuracy …

Abstract The Dark Energy Spectroscopic Instrument (DESI) survey is a spectroscopic survey
of tens of millions of galaxies at 0< z< 3.5 covering 14,000 sq. deg. of the sky. In its first 1.1 yr …

We present the first detection of the baryon acoustic oscillations (BAOs) signal obtained
using unblinded data collected during the initial 2 months of operations of the Stage-IV …

Abstract The Dark Energy Spectroscopic Instrument (DESI) is currently measuring the
spectra of 40 million galaxies and quasars, the largest such survey ever made to probe the …
