Star clusters stand at the intersection of much of modern astrophysics: the ISM, gravitational
dynamics, stellar evolution, and cosmology. Here, we review observations and theoretical …

We present a technique-led review of the progression of precise radio astrometry, from the
first demonstrations, half a century ago, until to date and into the future. We cover the …

Previous analyses of various standard candles observed by the Gaia satellite have reported
statistically significant systematics in the parallaxes that have improved from∼ 250 μas in …

In this study, we follow up our recent paper (Monteiro et al.) and present a homogeneous
sample of fundamental parameters of open clusters in our Galaxy, entirely based on Gaia …

The Gaia mission has opened a new window into the internal kinematics of young star
clusters at the sub-km s− 1 level, with implications for our understanding of how star clusters …

Water is a fundamental molecule in the star and planet formation process, essential for
catalysing the growth of solid material and the formation of planetesimals within disks …

We present a unified description of the scenario of global hierarchical collapse (GHC). GHC
constitutes a flow regime of (non-homologous) collapses within collapses, in which all …

We present a uniform catalog of accurate distances to local molecular clouds informed by
the Gaia DR2 data release. Our methodology builds on that of Schlafly et al. First, we infer …

Gaia DR2 provides unprecedented precision in measurements of the distance and
kinematics of stars in the solar neighborhood. Through applying unsupervised machine …

Giant molecular clouds (GMCs) are the sites of star formation and stellar feedback in
galaxies. Their properties set the initial conditions for star formation and their lifecycles …
