Transient sky with Gaia

13 Oct 2022, 08:00 → 14 Oct 2022, 23:00 Europe/Lisbon

Dep. of Physics of the University of Coimbra

Sonia Anton

The main goal of this meeting is to discuss phenomena related to transient sky, in the framework of Gaia (ESA) data. Gaia mission is an all-sky survey, that has been obtaining multi-epoch data for a range of objects (from solar system to extragalactic ones), the data having superb astrometric accuracy. Gaia mission can detect rapid to slowly transient phenomena, in scales of seconds, hours, weeks or years.

In this meeting we aim to discuss the latest results related to variable phenomena.  There will be presentations on Gaia mission updates, including the Gaia alerts and detection issues (models, calibrations, systematics). Scientific program includes sessions on regular variable stars, supernovae and local cosmology,  tidal disruption events, GW events, AGN variability and its impact on the definition of the celestial reference frames. We will also discuss the synergies between Gaia and  near future facilities like EUCLID (ESA), PLATO (ESA), Rubin and SKA Observatory.

The meeting is part of the project “Revealing the Milky Way with Gaia” (MW-Gaia) funded by a COST (European Cooperation in Science and Technology) Union action.
