Astro-GR@北京 (Beijing) 2012: Black Hole Growth in the Universe



of super- and massive black holes and their environment, organised by Pau Amaro-Seoane, Rainer Spurzem, Yun-Kau Lau and Fukun Liu.




Dense stellar systems such as galactic nuclei and massive stellar clusters, like globular or starburst clusters are unique laboratories for astrophysics. The high stellar densities that are found in their centers are at least a million times higher than in the solar neighbourhood. Therefore, the interaction among stars plays a dominant role in the global evolution of such systems. Observations of EM and GW sources could provide invaluable information on the astrophysical properties of stellar-mass binaries, as well as galaxy formation models with the coalescence of massive black holes, while captures of small compact objects by them will give us an exquisite information on the strong field regime around a Kerr black hole and the dark stellar population of galactic nuclei, as well as how stars distribute around the hole.


A particular interesting observatory is the Evolved Laser Interferometer Space Antenna (eLISA), which promises to open a completely new window into the heart of the most energetic processes in the universe, with consequences fundamental to both physics and astrophysics. eLISA is expected to detect gravitational waves from the coalescence of massive black holes in galaxies at cosmological distances and from stellar-mass black holes and neutron stars as they plunge onto massive black holes in nearby galaxies.

The workshop will focus on

  1. Observations and modelling of our own Galactic Center (SgrA*)
  2. Astrophysical modelling of super- and massive black hole coalescences
  3. Tidal disruptions of stars and gravitational capture of compact objects (EMRIs)
  4. Modelling of strong field sources within General Relativity
  5. Stellar-mass binaries
