Chronology Protection of Rotating Black Holes in a Viable Lorentz-Violating Gravity
Mu-In Park, Hideki Maeda
We study causal properties of the recently found rotating black-hole solution in the low-energy sector of Horava gravity as a viable Lorentz-violating (LV) gravity in four dimensio…

Exact plane symmetric black bounce with a perfect-fluid exterior obeying a linear equation of state
Hideki Maeda, Cristian Martinez
We investigate an exact two-parameter family of plane symmetric solutions admitting a hypersurface-orthogonal Killing vector in general relativity with a perfect fluid obeying a li…

Planar black holes and wormholes with a flat exterior
Hideki Maeda, Cristian Martinez
We present -dimensional planar black holes and wormholes with a flat exterior, which are originated by an exact solution in general relativity. The nonvacuum regions of t…
