Abstract |
Accretion flows around black holes are supposed to undergo centrifugal pressure supported shock transitions. The post-shock flow adequately mimics the properties of Comptonizing corona around accretion discs as far as the radiative properties are concerned. These normally dissipative shocks can also act as the base of the outflows and jets. The integrated radiative loss in the form of X-ray/gamma-ray from the Compton cloud or the radio emission from the jets would be expected to be correlated with the maximum available power at the dissipative shock. Here we compare observed radio and gamma-ray emission from several black hole candidates with the maximum energy that could be released from the post-shock region. We explain observed correlation between radio and mass of the black holes for microquasars and low luminosity AGNs. Similarly correlations with mass of gamma-ray emissions from these objects are also explained. |
