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 …

Dark matter represents currently an outstanding problem in both cosmology and particle
physics. In this review we discuss the possible explanations for dark matter and the …

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 …

We report on the discovery of two low-luminosity, broad-line active galactic nuclei (AGNs) at
z> 5 identified using JWST NIRSpec spectroscopy from the Cosmic Evolution Early Release …

Abstract The James Webb Space Telescope is revealing a new population of dust-reddened
broad-line active galactic nuclei (AGN) at redshifts z≳ 5. Here we present deep …

Wide-field imaging and spectroscopy enable a host of astrophysical studies that range from
the largest cosmological scales to the local environment of the Milky Way. Starting in 2000 …

We update the capabilities of the open-knowledge software instrument Modules for
Experiments in Stellar Astrophysics (MESA). The new auto _ diff module implements …

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 …

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 …

Prediction-powered inference is a framework for performing valid statistical inference when
an experimental dataset is supplemented with predictions from a machine-learning system …
