Squashed black holes at large
Ryotaku Suzuki, Shinya Tomizawa
Using the large effective theory approach, we construct a static solution of non-extremal and squashed black holes with/without an electric charge, which describes a spherical…
Lower bound for angular momenta of microstate geometries in five dimensions
Shinya Tomizawa
We study the BPS solutions of the asymptotically flat, stationary microstate geometries with bi-axisymmetry and reflection symmetry in the five-dimensional ungauged minimal supergr…
Stable circular orbits in Kaluza-Klein black hole spacetimes
Shinya Tomizawa, Takahisa Igata
Reducing motion of particles to a two-dimensional potential problem, we show that there are stable circular orbits around a squashed Kaluza-Klein black hole with a spherical horizo…
Stable circular orbits in caged black hole spacetimes
Takahisa Igata, Shinya Tomizawa
We consider the motion of massive and massless particles in a five-dimensional spacetime with a compactified extra-dimensional space where a black hole is localized, i.e., a caged…
