Abstract The standard Λ Cold Dark Matter (ΛCDM) cosmological model provides a good
description of a wide range of astrophysical and cosmological data. However, there are a …

We review applications of string theory to cosmology, from primordial times to the present-
day accelerated expansion. Starting with a brief overview of cosmology and string …

We present cosmological results from the measurement of baryon acoustic oscillations
(BAO) in galaxy, quasar and Lyman-α forest tracers from the first year of observations from …

Abstract The Dark Energy Spectroscopic Instrument (DESI) was designed to conduct a
survey covering 14,000 deg 2 over 5 yr to constrain the cosmic expansion history through …

The goal of the Dark Energy Spectroscopic Instrument (DESI) is to determine the nature of
dark energy through the most precise measurement of the expansion history of the universe …

The cosmological principle (CP)—the notion that the Universe is spatially isotropic and
homogeneous on large scales—underlies a century of progress in cosmology. It is …

▪ The Hubble parameter, H 0, is not an univocally defined quantity: It relates redshifts to
distances in the near Universe, but it is also a key parameter of the ΛCDM standard …

A number of challenges to the standard Λ CDM model have been emerging during the past
few years as the accuracy of cosmological observations improves. In this review we discuss …

We present the measurement of Baryon Acoustic Oscillations (BAO) from the Lyman-α (Lyα)
forest of high-redshift quasars with the first-year dataset of the Dark Energy Spectroscopic …

Abstract The Dark Energy Spectroscopic Instrument (DESI) is carrying out a five-year survey
that aims to measure the redshifts of tens of millions of galaxies and quasars, including 8 …
