"Heating
of interstellar medium by X-ray radiation from quasars, S. Yu. Sazonov (IKI) Abstract: Based on the second half of the thesis, the following questions will be addressed:
The problem about the emission spectrum of a typical quasar in the
Universe is formulated and solved; it is shown that Compton and
photoionization heating in the radiation field of such sources
can unbind interstellar gas from the potential
wells of giant elliptical galaxies. As a
consequence, the observed corellation between the stellar
velocity dispersions of galactic bulges and their central black
holes' masses could result from the radiative
feedback of accretion onto supermassive black
holes. |
