Braking--Radiation: An Energy Source for a Relativistic Fireball
C. Barrabes, P. A. Hogan
If the Schwarzschild black-hole is moving rectilinearly with uniform 3-velocity and suddenly stops, according to a distant observer, then we demonstrate that this observer will see…
Bursts of Radiation and Recoil Effects in Electromagnetism and Gravitation
C. Barrabès, P. A. Hogan
The Maxwell field of a charge e which experiences an impulsive acceleration or deceleration is constructed explicitly by subdividing Minkowskian space-time into two halves bounded…
Colliding Plane Impulsive Gravitational Waves
C. Barrabès, G. F. Bressange, P. A. Hogan
When two non-interacting plane impulsive gravitational waves undergo a head-on collision, the vacuum interaction region between the waves after the collision contains backscattered…
Stochastically Fluctuating Black-Hole Geometry, Hawking Radiation and the Trans-Planckian Problem
C. Barrabes, V. Frolov, R. Parentani
We study the propagation of null rays and massless fields in a black hole fluctuating geometry. The metric fluctuations are induced by a small oscillating incoming flux of energy.…
