Bremsstrahlung Effects around Evaporating Black Holes

Understand

We discuss a variety of bremsstrahlung processes associated with charged particles emitted by evaporating black holes.

• We show that such particles produce a negligible number of bremsstrahlung photons from their scattering off each other, though at low frequencies inner bremsstrahlung photons dominate over the direct Hawking emission of photons.
• This analysis and the further analysis of the accompanying paper invalidate Heckler's claim that sufficiently hot evaporating black holes form QED photospheres.
