Astrometry and Astrophysics in the Gaia sky (IAUS 330)
The ESA Gaia mission is astrometrically, photometrically and spectroscopically surveying the full sky since July 2014. This survey will be complete to magnitude 20 for the astrometry and photometry and to magnitude 16 for the spectroscopy (~1 billion and ~150 million sources expected, respectively). The first Gaia data release (GDR1) is foreseen for mid-2016.
This IAU Symposium (IAUS 330) will be the occasion to review the first 2.5 years of Gaia activities and to present and discuss the first scientific results derived from GDR1, about six months after its delivery. The symposium will also prepare the astronomical community for the scientific exploitation of the second data release, planned a couple of months after the symposium.
