| Research Abstract |
(1) We simulated gas flow onto binary black holes (pair of black holes) for given black hole masses,orbital eccentricities, and tilt angles of the disk, thereby clarifying their emission properties.(2) We calculated emission line profiles based on the SPH simulations of binary black holes, andreproduced observed, asymmetric double-peak profiles.(3) We performed global radiation-magnetohydrodynamic simulations of supercritical accretion flow,which is expected to occur in black hole mergers, and found an evidence of clumpy outflow.
