Absorption spectrum and greybody factors of charged black holes in loop quantum gravity
Marco A. A. de Paula, Valdir B. Bezerra, Luiz C. S. Leite
In the last few decades, singularity-free black holes (BHs) obtained in the framework of Loop Quantum Gravity (LQG) have gained attention in the literature. These compact objects r…

Sufficient conditions for unbounded superradiance in black hole spacetimes sourced by nonlinear electrodynamics
Marco A. A. de Paula, Luiz C. S. Leite, LuÃs C. B. Crispino
Recently, it has been reported that black holes (BHs) sourced by nonlinear electrodynamics (NED) can trigger unbounded superradiance, i. e., the total absorption cross section -- t…
