How quantum gravity tweaks what black holes radiate

When a dimensionless 'holonomy' parameter from loop quantum gravity is added to the standard Schwarzschild black hole, the three types of radiation it emits behave differently: low-energy scalar waves become more transparent, electromagnetic emission is the most strongly quenched, and fermions end up dominating once the correction is appreciable. The black hole also runs cooler, so thermal suppression cuts the total output. These calculations offer concrete spectral signatures that could, in principle, distinguish quantum-gravity-corrected black holes from classical ones.
