Bremsstrahlung by static charges outside a static black hole ?
G. E. Matsas, D. Sudarsky, A. Higuchi
Abstract
We show that in complete analogy with the usual bremsstrahlung process, when studied from the coaccelerated observer's point of view, a charge moving along the integral curves of the static Killing field in the exterior of a static black hole gives rise to the emission of zero-energy photons, induced by the thermal bath of Hawking Radiation.
