Gaia Data Release 1: Astrometry - one billion positions, two million proper motions and parallaxes
L. Lindegren, U. Lammers, U. Bastian +80
Gaia Data Release 1 (Gaia DR1) contains astrometric results for more than 1 billion stars brighter than magnitude 20.7 based on observations collected by the Gaia satellite during…
On-orbit performance of the Gaia CCDs at L2
C. Crowley, R. Kohley, N. C. Hambly +19
The European Space Agency's Gaia satellite was launched into orbit around L2 in December 2013 with a payload containing 106 large-format scientific CCDs. The primary goal of the mi…
Gaia Data Release 1. Summary of the astrometric, photometric, and survey properties
Gaia Collaboration, A. G. A. Brown, A. Vallenari +5
At about 1000 days after the launch of Gaia we present the first Gaia data release, Gaia DR1, consisting of astrometry and photometry for over 1 billion sources brighter than magni…
Kinematics of symmetric Galactic longitudes to probe the spiral arms of the Milky Way with Gaia
T. Antoja, S. Roca-Fabrega, J. de Bruijne +1
We model the effects of the spiral arms of the Milky Way on the disk stellar kinematics in the Gaia observable space. We also estimate the Gaia capabilities of detecting the predic…
