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.
