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 …

The cold interstellar medium (ISM) plays a central role in the galaxy evolution process. It is
the reservoir that fuels galaxy growth via star formation, the repository of material formed by …

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 …

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

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 …

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) …

We present a joint cosmological analysis of weak gravitational lensing observations from the
Kilo-Degree Survey (KiDS-1000), with redshift-space galaxy clustering observations from …

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 …

ABSTRACT I introduce some improvements to the ppxf method, which measures the stellar
and gas kinematics, star formation history (SFH) and chemical composition of galaxies. I …
