What happens to Petrov classification on horizons of axisymmetric dirty black holes
I. V. Tanatarov, O. B. Zaslavskii
We consider axisymmetric stationary dirty black holes with regular non-extremal or extremal horizons, and compute their on-horizon Petrov types. The Petrov type (PT) in the frame o…
Acceleration of particles by quasiblack holes
O. B. Zaslavskii
If two particles collide near the black hole horizon, the energy in the centre of mass (CM) frame can grow indefinitely (the so-called the BSW effect). This requires fine-tuning th…
Energy extraction from extremal charged black holes due to the BSW effect
O. B. Zaslavskii
Two particles can collide in the vicinity of a rotating black hole producing the divergent energy in the centre of mass frame (the BSW effect). However, it was shown recently that…
Dirty rotating black holes: regularity conditions on stationary horizons
I. V. Tanatarov, O. B. Zaslavskii
We consider generic, or "dirty" (surrounded by matter), stationary rotating black holes with axial symmetry. The restrictions are found on the asymptotic form of metric in the vici…
Energetics of particle collisions near dirty rotating extremal black holes: Banados-Silk-West effect versus Penrose process
O. B. Zaslavskii
If two particles collide near the horizon of a rotating extremal black hole, under certain conditions the energy E_{c.m.} in the center-of-mass frame can grow without limit (the so…
Circular orbits and acceleration of particles by near-extremal dirty rotating black holes: general approach
O. B. Zaslavskii
We study the effect of ultra-high energy particles collisions near the black hole horizon (BSW effect) for two scenarios: when one of particle either (i) moves on a circular orbit…
