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 …

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 …

Context. Gaia Early Data Release 3 (Gaia EDR3) contains results for 1.812 billion sources in
the magnitude range G= 3–21 based on observations collected by the European Space …

Context. Gaia Early Data Release 3 (Gaia EDR3) gives trigonometric parallaxes for nearly
1.5 billion sources. Inspection of the EDR3 data for sources identified as quasars reveals …

We use the data from Gaia Early Data Release 3 (EDR3) to study the kinematic properties of
Milky Way globular clusters. We measure the mean parallaxes and proper motions (PM) for …

Context. Gaia Data Release 2 (Gaia DR2) contains results for 1693 million sources in the
magnitude range 3 to 21 based on observations collected by the European Space Agency …

The assembly of our Galaxy can be reconstructed using the motions and chemistry of
individual stars1, 2. Chemo-dynamical studies of the stellar halo near the Sun have …

We assemble a catalogue of candidate Sagittarius stream members with 5D and 6D phase-
space information, using astrometric data from Gaia DR2, distances estimated from RR …

Abstract The Gaia Sausage is the major accretion event that built the stellar halo of the Milky
Way galaxy. Here, we provide dynamical and chemical evidence for a second substantial …

Context. The second Gaia data release (DR2) contains very precise astrometric and
photometric properties for more than one billion sources, astrophysical parameters for …
