Abstract: | Correlations of active galactic nuclei (AGNs) with microquasars are
discussed based on the coexistence of the Blandford--Znajek (BZ) and
magnetic coupling (MC) processes (CEBZMC) in black hole (BH)
accretion disk. The proportions of several quantities of BH systems
for both AGNs and microquasars are derived by combining the
observational data with CEBZMC. It is shown that the square of the
magnetic field at the BH horizon is inversely proportional to the BH
mass, while the accretion rate of the disk is proportional to the BH
mass. In addition, the very steep emissivity indexes from the recent
XMM-Newton observations of the nearby bright Seyfert 1
galaxy MCG-6-30-15 and the microquasars XTE J1650-500 are well
fitted by considering the MC effects on the disk radiation. These
results suggest strongly the correlations of AGNs with microquasars. |
