The advent of the second data release of the Gaia mission, in combination with data from
large spectroscopic surveys, is revolutionizing our understanding of the Galaxy. Thanks to …

Our Galaxy, the Milky Way, is a benchmark for understanding disk galaxies. It is the only
galaxy whose formation history can be studied using the full distribution of stars from faint …

We present an investigation into the first 500 Myr of galaxy evolution from the Cosmic
Evolution Early Release Science (CEERS) survey. CEERS, one of 13 JWST ERS programs …

The ensemble of chemical element abundance measurements for stars, along with precision
distances and orbit properties, provides high-dimensional data to study the evolution of the …

We construct from Gaia eDR3 an extensive catalogue of spatially resolved binary stars
within≈ 1 kpc of the Sun, with projected separations ranging from a few au to 1 pc. We …

We compile and analyze approximately 200 trigonometric parallaxes and proper motions of
molecular masers associated with very young high-mass stars. Most of the measurements …

We present a new cosmological, magnetohydrodynamical simulation for galaxy formation:
TNG50, the third and final instalment of the IllustrisTNG project. TNG50 evolves 2× 21603 …

Abstract The DESI Legacy Imaging Surveys (http://legacysurvey. org/) are a combination of
three public projects (the Dark Energy Camera Legacy Survey, the Bei**g–Arizona Sky …

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 …

ABSTRACT We determine the Milky Way (MW) mass profile inferred from fitting physically
motivated models to the Gaia DR2 Galactic rotation curve and other data. Using various …
