The appearance of very high red-shift quasars and the formation of super massive black holes
Pavel Kroupa (Universität Bonn)
Quasars are found to appear a few hundred Myr after the Big
Bang, but pressing matter together into super-massive black holes
(SMBHs) so quickly appears to be impossible. At a later stage, the
spheroidal component of a galaxy (its bulge if it is not an elliptical
galaxy) is observed to show a correlation between its mass and that of
the central SMBH it harbours, although spheroids with a mass lower than
a few 1E9 Msun appear to only host a nuclear star cluster. I will
discuss a theory for the formation of SMBHs which accounts for these
observations using standard, non-exotic physics.
