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 …

Terahertz (THz) radiation encompasses a wide spectral range within the electromagnetic
spectrum that extends from microwaves to the far infrared (100 GHz–∼ 30 THz). Within its …

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 cosmological results from the measurement of baryon acoustic oscillations
(BAO) in galaxy, quasar and Lyman-$\alpha $ forest tracers from the first year of …

Gamma-ray bursts (GRBs) are divided into two populations,; long GRBs that derive from the
core collapse of massive stars (for example, ref.) and short GRBs that form in the merger of …

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 …

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) …

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 mergers of binary compact objects such as neutron stars and black holes are of central
interest to several areas of astrophysics, including as the progenitors of gamma-ray bursts …
