| Outline of Final Research Achievements |
On the contrary to the classical belief that there exists a maximum limit to the gas accretion rate onto a black hole, recent simulation studies have established that supercritical accretion exceeding the classical limit is feasible and that powerful outflow is driven by strong electromagnetic wave radiation from the flow. We performed more sophisticated simulations, finding observational signatures of supercritical accretion and the conditions for the rapid growth of seed black holes in early universe. We have also developed the methodologies to investigate the space-time structure, gas flow dynamics, and magnetic field configurations around black holes.
