Event Details & Abstract: 

Several new techniques are currently being employed to probe the strong gravitational field in the vicinity of supermassive black holes. Long baseline interferometry at sub-millimeter wavelengths constrains the silhouette of the black holes in the Galactic center (SgrA*) and M87. Stars which get tidally disrupted as they orbit too close to a single black hole are being discovered at cosmological distances. Electromagnetic counterparts of black hole binaries in galaxy mergers are being identified, and can be used to calibrate the rate of gravitational wave sources for eLISA/NGO. Most interestingly, the recoil induced by the anisotropic emission of gravitational waves in the final plunge of binaries leaves unusual imprints on their host galaxies.
