The Dirac and Klein-Gordon equations and Greybody Radiation for the Regular Hayward Black Hole
Ahmad Al-Badawi
We investigate the Dirac and Klein-Gordon equations, as well as greybody radiation, for the Hayward black hole (BH) spacetime. We first consider the Dirac equation using a null tet…

Greybody factor and perturbation of a Schwarzschild black hole with string clouds and quintessence
Ahmad Al-Badawi
In this paper, we investigated the Dirac and Klein-Gordan equations, as well as the greybody factor for a Schwarzschild black hole (SBH) immersed in quintessence and associated wit…
