Molecular hydrogen is the most abundant molecule in the universe. It is the first one to form
and survive photo-dissociation in tenuous environments. Its formation involves catalytic …

This article gives an overview of the constitution, physical conditions, and observables of
dust in the interstellar medium of nearby galaxies. We first review the macroscopic, spatial …

We present a new three-dimensional map of dust reddening, based on Gaia parallaxes and
stellar photometry from Pan-STARRS 1 and 2MASS. This map covers the sky north of a decl …

Euclid is a mission of the European Space Agency that is designed to constrain the
properties of dark energy and gravity via weak gravitational lensing and galaxy clustering. It …

We study the large-scale anisotropy of the universe by measuring the dipole in the angular
distribution of a flux-limited, all-sky sample of 1.36 million quasars observed by the Wide …

Abstract We describe the Dark Energy Survey (DES) photometric data set assembled from
the first three years of science operations to support DES Year 3 cosmologic analyses, and …

We present the first joint analysis of catalogs of radio galaxies and quasars to determine
whether their sky distribution is consistent with the standard ΛCDM model of cosmology …

We develop, validate and apply a forward model to estimate stellar atmospheric parameters
(T eff, log g, and [Fe/H]), revised distances and extinctions for 220 million stars with XP …

The region around the Galactic Center (GC) is now well established to be brighter at
energies of a few GeV than what is expected from conventional models of diffuse gamma …

We present a three-dimensional map of interstellar dust reddening, covering three-quarters
of the sky out to a distance of several kiloparsecs, based on Pan-STARRS 1 (PS1) and …
