Collision energy of particles in the ergosphere of rotating black holes

  • A. A. Grib
  • Yu. V. Pavlov


We give new estimates for the possibility that a resonance appears in the center-of-mass system when particles collide in the ergospheres of rotating black holes—active galactic nuclei. We investigate a new effect: an increase in the center-of-mass energy depending on the particle angular momentum, which can occur at any point of the ergosphere.
