For the first time, we have explored the spatial substructure of the Cygnus OB2 association using parallaxes from the recent second Gaia data release. We find significant line-of-sight substructure within the association, ...
The Gaia/IPHAS and Gaia/KIS value-added catalogues
(2018-12-11)
We present a sub-arcsecond crossmatch of Gaia DR2 against the INT Photometric Ha Survey of the Northern Galactic Plane Data Release 2 (IPHAS DR2) and the Kepler-INT Survey (KIS). The resulting value-added catalogues (VACs) ...
