A Proposed Program of Observations of Extragalactic X-Ray Sources
Abstract
It is proposed to carry out an observational test of the hypothesis that active galactic nuclei contain a massive black hole, surrounded by an accretion disk as an energy source. The observational program included 64 objects, selected according the Aldrovandi's model.
