Special Session Sp3
1 July 2014
Tidal disruption events around Sgr A* and beyond
Aims and scope
Most supermassive black holes in the Universe are dormant and starved. Sometimes, unlucky objects like
stars or planets, closely approaching black holes, are torn apart by tidal forces. Part of the debris are
consumed by the black hole resulting in luminous flares of radiation. 35 years ago, tidal disruption events
were predicted to become signposts of super massive black holes at the cores of non-active galaxies, out to
high redshifts. They now also provide new probes of strong gravity, and have opened up a new window to
study accretion physics and jet formation.
This special session will focus on Sgr A* and on the dynamic of the G2 gas cloud, offering a chance to resolve
the capture and the swallowing of gas by a nearby black-hole and on recent well sampled extragalactic tidal
disruption events, revealing new phenomena, and on their confrontation to state-of-the-art hydrodynamical
models.
