The seminar is supported by the grant of Federal Programm "Integration" . ... Measuring the Hubble Constant from Reverberating Accretion Discs in AGNs . We show how wavelength-dependent time delays between continuum flux variations of active galactic nuclei (AGNs) can be used to test the standard black hole--accretion disc paradigm, by measuring the temperature structure T(R) of the gaseous material surrounding the purported black hole. ...
