Scientific Rationale

Quasars and AGN’s (~500 000) are with stars (~1 billion), the most fascinating targets up to be collected by the Gaia satellite which constitutes a fully funded ESA 'Cornerstone' mission. This mission, typically built for quasi-punctual sources, will detect over the whole sky and with an exceptional accuracy quasars as well as bright and compact AGNs on the deepest z-coverage.

The science with quasars brings fundamental bases to build reference systems as well as to link supermassive black holes and star formation histories at the earliest epochs. The GAGNES meeting concerns a large community of scientific researchers and engineers involved and/or interested by Gaia data (analysis, mining, physics). On the other hand, the GAGNES meeting will gather the widest community on various topics for the science exploitation and complementary programs.

This meeting is the opportunity to gather ~50 participants, including members of the Gaia- DPAC, young students, post-docs and experts, in the continuity of the four successful EGSG (ExtraGalactic Science with Gaia) meetings already organized at the Institut d'Astrophysique de Paris, Observatoire de Paris and Observatoire de La Côte d'Azur.
