Strong lensing and Hawking spectra of charged black hole under Lorentz violation theory

Yenshembam Priyobarta Singh, Ningthoujam Media, Telem Ibungochouba Singh

In this paper, we investigate the strong gravitational lensing effects around the Reissner-Nordstr{ö}m-like black hole (RN-like BH) in bumblebee gravity. We calculate the lensing…
