Disentangling the spatial substructure of Cygnus OB2 from Gaia DR2
(2019-04-01)
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, ...
Parallaxes of southern extremely cool objects III : 118 L and T dwarfs
(2018-12-11)
We present new results from the Parallaxes of Southern Extremely Cool dwarfs program to measure parallaxes, proper motions and multiepoch photometry of L and early T dwarfs. The observations were made on 108 nights over ...
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) ...
3D shape of Orion A from Gaia DR2
(2018-11-14)
We use the Gaia DR2 distances of about 700 mid-infrared selected young stellar objects in the benchmark giant molecular cloud Orion A to infer its 3D shape and orientation. We find that Orion A is not the fairly straight ...
VIRAC: The VVV Infrared Astrometric Catalogue
(2018-02-21)
We present VIRAC version 1, a near-infrared proper motion and parallax catalogue of the VISTA Variables in the Via Lactea (VVV) survey for 312 587 642 unique sources averaged across all overlapping pawprint and tile images ...
