Cosmic-ray astrophysics has advanced rapidly in recent years, and its impact on other
astronomical disciplines has broadened. Many new experiments measuring these particles …

We present a catalogue of white dwarf candidates selected from Gaia Early Data Release 3
(EDR3). We applied several selection criteria in absolute magnitude, colour, and Gaia …

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 …

Context. The multiplicity fraction of stars, down to the substellar regime, is a parameter of
fundamental importance for stellar formation, evolution, and planetology. The census of …

Context. The census of stellar and substellar companions of nearby stars is largely
incomplete, in particular toward the low-mass brown dwarf and long-period exoplanets. It is …

The second Gaia data release (Gaia DR2) contains, beyond the astrometry, three-band
photometry for 1.38 billion sources. One band is the G band, the other two were obtained by …

We present a new model for the distribution of free electrons in the Galaxy, the Magellanic
Clouds, and the intergalactic medium (IGM) that can be used to estimate distances to real or …

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 …

We present a new 3D map of interstellar dust reddening, covering three quarters of the sky
(declinations of δ≳− 30°) out to a distance of several kiloparsecs. The map is based on high …

Combining the precise parallaxes and optical photometry delivered by Gaia's second data
release with the photometric catalogues of Pan-STARRS1, 2MASS, and AllWISE, we …
