| Abstract: | Black holes are the most compact objects in the universe. Therefore, matter accreting onto them is likely to radiate photons
of energy comparable to very high gravitational potential energy. We discuss the nature of the emitted radiation in X-rays
and gamma-rays from black hole candidates. We present theoretical solutions, which comprise both Keplerian and sub-Keplerian
components and suggest that shocks in accretion and outflows may play a major role in producing these spectra. |
