Testing loop quantum gravity by quasi-periodic oscillations: rotating blackholes by Jafar Khodagholizadeh, Ghadir Jafari, Alireza Allahyari, Ali Vahedi

“…Abstract We investigate a compelling model of a rotating black hole that is deformed by the effects of loop quantum gravity (LQG). We present a simplified metric and explore two distinct geometries: one in which the masses of the black hole and white hole are equal, and another in which they differ. …”
