Multi-rotating black holes with non-aligned angular momenta in 5D Kaluza-Klein theory
Shinya Tomizawa, Hideo Furugori, Jun-ichi Sakamoto +1
The paper derives an exact multi‑centered solution for rotating black holes with non‑aligned angular momenta in 5‑dimensional Kaluza‑Klein theory, which reduces to a 4‑dimensional…
Multi--black holes in Bertotti--Robinson spacetime
Hideo Furugori, Jun-ichi Sakamoto, Shinya Tomizawa
We construct a new class of exact solutions describing multi-black holes in the Bertotti--Robinson spacetime, using the monodromy-matrix formalism associated with integrable sigma…
Monodromy-Matrix Description of Extremal Multi-centered Black Holes
Jun-ichi Sakamoto, Shinya Tomizawa
We study solution-generating techniques based on the Breitenlohner--Maison linear system for extremal, stationary biaxisymmetric black hole solutions in five-dimensional s…
Existence conditions of nonsingular dyonic black holes in nonlinear electrodynamics
Ren Tsuda, Ryotaku Suzuki, Shinya Tomizawa
General relativity coupled to nonlinear electrodynamics is known to have nonsingular black hole solutions. We investigate the existence conditions for such solutions in two-paramet…
Multi-centered Myers-Perry Black Holes in Five Dimensions
Shinya Tomizawa, Jun-ichi Sakamoto, Ryotaku Suzuki
We present a new family of multi-centered rotating black hole solutions in 5D vacuum Einstein gravity, providing explicit examples of cohomogeneity-three spacetimes. It is well kno…
Fan-Wang type regular black holes in Quasi-Topological Gravity
Ren Tsuda, Ryotaku Suzuki, Shinya Tomizawa
We construct a class of regular black hole solutions of the Fan-Wang type within quasi-topological gravity (QTG) in arbitrary spacetime dimensions greater than four. In contrast to…
