Eclipsing Light-Curve Asymmetry for Black-Hole Accretion Flows
Ken-ya Watarai, Rohta Takahashi, Jun Fukue
We propose an eclipsing light-curve diagnosis for black-hole accretion flows. When emission from an inner accretion disk around a black hole is occulted by a companion star, the ob…

Black Hole Shadows of Charged Spinning Black Holes
Rohta Takahashi
We propose a method for measuring the black hole charge by imaging a black hole shadow in a galactic center by future interferometers. Even when the black hole is uncharged, it is…

Geometrical Effect of Supercritical Accretion Flows: Observational Implications of Galactic Black-Hole Candidates and Ultraluminous X-ray Sources
K. Watarai, K. Ohsuga, R. Takahashi +1
We investigate the dependence of the viewing angle in supercritical accretion flows and discuss the observational implications of galactic black-hole candidates and ultraluminous X…
