Query: Radiative Penrose process: Energy Gain by a Single Radiating Charged
  Particle in the Ergosphere of Rotating Black Hole   We demonstrate an extraordinary effect of energy gain by a single radiating
charged particle inside the ergosphere of a Kerr black hole in presence of
magnetic field. We solve numerically the covariant form of the Lorentz-Dirac
equation reduced from the DeWitt-Brehme equation and analyze energy evolution
of the radiating charged particle inside the ergosphere, where the energy of
emitted radiation can be negative with respect to a distant observer in
dependence on the relative orientation of the magnetic field, black hole spin
and the direction of the charged particle motion. Consequently, the charged
particle can leave the ergosphere with energy greater than initial in expense
of black hole's rotational energy. In contrast to the original Penrose process
and its various modification, the new process does not require the interactions
(collisions or decay) with other particles and consequent restrictions on the
relative velocities between fragments. We show that such a Radiative Penrose
effect is potentially observable and discuss its possible relevance in
formation of relativistic jets and in similar high-energy astrophysical
settings.
