Kerr-Sen dilaton-axion black hole lensing in the strong deflection limit
Galin N. Gyulchev, Stoytcho S. Yazadjiev
In the present work we study numerically quasi-equatorial lensing by the charged, stationary, axially-symmetric Kerr-Sen dilaton-axion black hole in the strong deflection limit. In…
Rotating dyonic dipole black rings: exact solutions and thermodynamics
Stoytcho S. Yazadjiev
New rotating dyonic dipole black ring solutions are derived in 5D Einstein-dilaton gravity with antisymmetric forms. The black rings are analyzed and their thermodynamics is discus…
Dilaton black holes with squashed horizons and their thermodynamics
Stoytcho S. Yazadjiev
New charged solutions describing black holes with squashed horizons in 5D dilaton gravity are presented. The black hole spacetimes are asymptotically locally flat and have a spacia…
Solution generating in 5D Einstein-Maxwell-dilaton gravity and derivation of dipole black ring solutions
Stoytcho S. Yazadjiev
We consider 5D Einstein-Maxwell-dilaton (EMd) gravity in spacetimes with three commuting Killing vectors: one timelike and two spacelike Killing vectors, one of which is hypersurfa…
Completely integrable sector in 5D Einstein-Maxwell gravity and derivation of the dipole black ring solutions
Stoytcho S. Yazadjiev
We consider 5D Einstein-Maxwell (EM) gravity in spacetimes with three commuting Killing vectors: one timelike and two spacelike Killing vectors one of them being hypersurface-ortho…
