Outline of Final Research Achievements

We have been working on multi-dimensional radiation-hydrodynamic simulations of supercritical accretion, accretion flow onto compact objects at rates exceeding the classical limit, and have so far clarified its various unique features, such as clumpy outflow. Here, we focus on the effects of supercritical accretion on the cosmological evolution of black holes, and (1) found eruption of neutral outflow from an intermediate-mass black hole via radiation feedback, (2) reproduced the enigmatic hard X-ray spectra by calculating deformation of spectra by multiple Compton scatterings, and (3) performed numerical simulations of accretion onto binary black holes. Finally, we also clarified the central engine of the Ultraluminous X-ray pulsars by calculating the flow dynamics of supercritical accretion column.
