Determining parameters of Kerr black holes at finite distance by shadow observation

Kenta Hioki, Umpei Miyamoto

We propose a new method to determine the physical parameters of Kerr black holes (namely, specific angular momentum , inclination angle , and distance from an observer) o…

Determining parameters of a spherical black hole with a thin accretion disk by observing its shadow

Kenta Hioki, Umpei Miyamoto

We revisit the classic system of a spherically symmetric black hole in general relativity (i.e., a Schwarzschild black hole) surrounded by a geometrically thin accretion disk. Our…

Dynamical Transition from a Naked Singularity to a Black Hole

Kenta Hioki, Tomohiro Harada

We show that a Reissner-Nordström (RN) black hole can be formed by dropping a charged thin dust shell onto a RN naked singularity. This is in contrast to the fact that a RN naked s…
