GUP effects on Hawking temperature in a hot NUT Kerr Newman Kasuya Anti de Sitter black hole

In this work, we use the generalised Klein-Gordon Equation in curved spacetime with an electromagnetic field to investigate the tunnelling phenomenon of scalar particles originating from the hot NUT Kerr Newman Kasuya Anti de Sitter (KNKNK AdS) black hole. Using the tunnelling formalism, we obtain a modified Hawking temperature different from previous works due to the quantum gravity effect for the charged Dirac particle at the HNKNK AdS black hole's horizon. We find that the modified Hawking temperature is affected by the cosmological constant, magnetic mass, electric and magnetic charges. We demonstrate that a significant number of discontinuities exist in the heat capacities of the HNKNK AdS, indicating that the black hole system becomes unstable as the black hole size decreases.

Hawking radiation from a hot NUT-Kerr-Newman-Kasuya-Anti-de Sitter black hole

In this work, we investigate the tunneling phenomenon of a charged Dirac particle emerging from a thermal horizon of a hot NUT-Kerr-Newman-Kasuya-Anti-de Sitter (HNKNK-AdS) black hole. Considering the tunneling formalism, we report the Hawking temperature of the charged Dirac particle through the horizon and the heat capacity of the HNKNK-AdS black hole. It is found that the effective Hawking temperature for the black hole depends on the black hole's parameters, such as electric and magnetic charges, magnetic mass, the cosmological constant, and the angular momentum of the black hole. The Hawking radiation for the Kerr-Newman black hole is reduced. It is shown that there is a small correction to the Hawking thermal spectrum. The heat capacity for the HNKNK-AdS black hole is found different from the previous work, and for the Kerr-Newman black hole is also reduced.
