Abstract: (ADS)
The formation of black holes with masses of the order of over 100,000 solar masses is noted to be possible upon the quasi-spherical collapse of gas clouds, on the basis of nonlinear density perturbations above the Jeans mass after the cosmological recombination. After the cloud has collapsed by a few order of magnitude in radius, the photons become trapped and transport angular momentum only locally, through radiative viscosity; the black hole produced when the cloud collapses quasi-spherically down to its Schwartzchild scale is surrounded by a dark-matter halo.References(16)
