Penrose photoproduction processes: A high efficiency energy mechanism for active galactic nuclei and quasars
Journal Article

Recent observations of NGC 4151 and 3C273 suggest that the nuclei of active galaxies have very high gamma ray efficiencies. In addition, optical studies of M87 have indicated the possibility of a massive Mapprox.5 x 10/sup 9/ M/sub sun/ black holes being present in its central region. The above facts have led us to study a new physical mechanism, Penrose Photoproduction Processes in the ergospheres of massive Kerr black holes, as a way to account for the fluctuating, high efficiency, energy production associated with active galaxies and quasars. Observational signatures, associated with this mechanism, occur in the form of approx.2 MeV and approx.2 GeV gamma ray cutoffs which might be corroborated by the observed spectra of NGC 4151 and 3C273, respectively.
