We study the thermodynamics of a non-singular black hole model with effective quantum corrections motivated by Loop Quantum Gravity (LQG). The effective geometry has a transition surface that connects trapped and anti-trapped regions with the same mass. There is a minimum mass for which the horizon temperature and Komar energy are zero, and the black hole stops its Hawking evaporation. For horizons above this limit, we present the grey-body factors, emission spectra, and the mass loss rate, solving a one-dimensional Schrdinger-type equation with an effective short-range potential barrier for massless fields of spins 0, 1/2, 1 and 2.

  1. Radiative properties of a nonsingular black hole: Hawking radiation and gray-body factor

    gr-qc 2025-04 conditional novelty 6.0 of 10

    A singularity-free black hole radiates more coldly and more like a perfect black body than Schwarzschild does, and, on one assumption about its parameters, it ends as a zero-temperature remnant instead of evaporating.

  2. Hawking evaporation and the fate of black holes in loop quantum gravity

    gr-qc 2025-04 conditional novelty 6.0 of 10

    In a covariant LQG black hole model, Hawking temperature is unchanged while greybody factors gain sub-leading corrections, and a derived mass hierarchy favors black-to-white-hole transitions over remnants.
