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 …

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 …

This paper documents the seventeenth data release (DR17) from the Sloan Digital Sky
Surveys; the fifth and final release from the fourth phase (SDSS-IV). DR17 contains the …

We present the cosmological implications from final measurements of clustering using
galaxies, quasars, and Ly α forests from the completed Sloan Digital Sky Survey (SDSS) …

ABSTRACT The European Space Agency's Planck satellite, which was dedicated to
studying the early Universe and its subsequent evolution, was launched on 14 May 2009. It …

The H0LiCOW collaboration inferred via strong gravitational lensing time delays a Hubble
constant value of km s− 1 Mpc− 1, describing deflector mass density profiles by either a …

The Sloan Digital Sky Surveys (SDSS) have been almost continuously observing the skies
for over 20 yr, since the project began with a first phase in 1998 (SDSS-I; York et al. 2000) …

The presence of excess scatter in the Ly-α forest at z∼ 5.5, together with the existence of
sporadic extended opaque Gunn-Peterson troughs, has started to provide robust evidence …

The discovery of a gravitational wave (GW) signal from a binary neutron star (BNS) merger
(Abbott et al. 2017a) and the kilonova emission from its remnant (Coulter et al. 2017; Abbott …

Abstract The Very Large Array Sky Survey (VLASS) is a synoptic, all-sky radio sky survey
with a unique combination of high angular resolution (≈ 2 farcs 5), sensitivity (a 1σ goal of …
