Kerr-Newman-Taub-Nut black hole tunneling radiation

The tunnelling processes generally occur near the outer horizon of the black hole (BH). We investigate the tunnelling radiation in the vicinity of the Kerr-Newman-Taub-NUT(KNTN) BH. In this article, the new coordinate system for the KNTN BH is introduced, which helps us to form a new line element. This line element helps us to show that the new coordinate is exhaustively acted at the outer horizon. We show that the Hawking's radiation is not entirely thermal with the help of the self-gravitational effect, energy, and conservation of angular momentum.
