Radiation of Quantized Black Hole
The maximum entropy of a quantized surface is demonstrated to be proportional
to the surface area in the classical limit. The general structure of the
horizon spectrum and the value of the Barbero-Immirzi parameter are found. The
discrete spectrum of thermal radiation of a black hole fits naturally the Wien
profile. The natural widths of the lines are very small as compared to the
distances between them. The total intensity of the thermal radiation is
calculated.Comment: 11 pages; few comments and a reference added; one more reference and

Quantized Black Holes, Their Spectrum and Radiation
Under quite natural general assumptions, the following results are obtained.

black hole Under quite natural general assumptions, the following results are
obtained. The maximum entropy of a quantized surface is demonstrated to be
proportional to the surface area in the classical limit. The general structure
of the horizon spectrum is found. The discrete spectrum of thermal radiation of
a black hole fits the Wien profile. The natural widths of the lines are much
smaller than the distances between them. The total intensity of the thermal
radiation is estimated.
In the special case of loop quantum gravity, the value of the Barbero --
Immirzi parameter is found. Different values for this parameter, obtained under
additional assumption that the horizon is described by a U(1) Chern -- Simons
theory, are demonstrated to be in conflict with the firmly established
holographic bound.Comment: 15 pages, content of few talks given at conferences this summe
