Strong cosmic censorship for the massless Dirac field in the Reissner-Nordstrom-de Sitter spacetime

Boxuan Ge, Jie Jiang, Bin Wang +2

We present the Fermi story of strong cosmic censorship in the near-extremal Reissner-Nordstrom-de Sitter black hole. To this end, we first derive from scratch the criterion for the…

Observational signature of near-extremal Kerr-like black holes in a modified gravity theory at the Event Horizon Telescope

Minyong Guo, Niels A. Obers, Haopeng Yan

We study the shadows cast by near-extremal Kerr-MOG black holes for different values of the parameter in modified gravity (MOG). In particular, we consider an isotropic emitter orb…
