Abstract The Laser Interferometer Space Antenna (LISA) will be a transformative experiment
for gravitational wave astronomy, and, as such, it will offer unique opportunities to address …

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 …

We present a 0.16% precise and 0.27% accurate determination of R 0, the distance to the
Galactic center. Our measurement uses the star S2 on its 16-year orbit around the massive …

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 …

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

Context. Gaia Data Release 2 provides high-precision astrometry and three-band
photometry for about 1.3 billion sources over the full sky. The precision, accuracy, and …

Context. With the most recent Gaia data release, the number of sources with complete 6D
phase space information (position and velocity) has increased to well over 33 million stars …

Gaia stellar measurements are currently revolutionizing our knowledge of the evolutionary
history of the Milky Way. 3D maps of the interstellar dust provide complementary information …

Aims. We produce a clean and well-characterised catalogue of objects within 100 pc of the
Sun from the Gaia Early Data Release 3. We characterise the catalogue through …

The vertical structure and dynamics of stars in our local Galactic neighbourhood contains
much information about the local distribution of visible and dark matter and of perturbations …
