Some aspects of black hole physics in loop quantum gravity | |||||

Abstract |
Some recent results on black holes in effective loop quantum gravity are presented. Quantum gravity effects might allow the transition of a black hole into a white hole, when the Planck density is reached. I briefly review previous studies and focus on the random nature of the bouncing lifetime which was not previously taken into account. I show that, when we consider a stochastic lifetime, the signal emitted by bouncing black holes might explain fast radio bursts. Then, I present new results on the absorption cross sections calculated for a quasi Schwarzschild black hole including loop quantum gravity corrections. The black hole geometry deformation due to quantum effect has consequences for the grey-body factors and the Hawking spectrum. |
