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…

Fake Schwarzschild and Kerr black holes
Hideki Maeda
We present exact solutions describing a fake Schwarzschild black hole that cannot be distinguished from the Schwarzschild black hole by observations. They are constructed by attach…
