Some aspects of black hole physics in loop quantum gravity

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 effects has consequences for the cross sections and the Hawking spectrum.
