Photon orbits and phase transition for gravitational decoupled Kerr anti-de Sitter black holes
Suhail Khan, Shafqat Ul Islam, Sushant G. Ghosh +1
Interpreting the cosmological constant as the energy of the vacuum and using a gravitational decoupling approach leads to a new Kerr--anti-de Sitter (AdS) black hole. The metric of…
