Effect of a Weak Electromagnetic Field on Particle Acceleration by a Rotating Black Hole
Weak Electromagnetic Field Particle Acceleration Rotating Black Hole
2012/2/23
We study high energy charged particle collisions near the horizon in an electromagnetic field around a rotating black hole and reveal the condition of the fine-tuning to obtain arbitrarily large cente...
Electromagnetic extraction of energy from merging black holes
Electromagnetic extraction merging black holes
2011/1/13
We calculate the evolution of the prompt intrinsic Poynting power generated by merging black holes. Orbiting black holes induce rotation of the space-time. In a presence of magnetic field supported by...
Electromagnetic Counterparts to Black Hole Mergers
High Energy Astrophysical Phenomena (astro-ph.HE)
2011/1/6
During the final moments of a binary black hole (BH) merger, the gravitational wave (GW) luminosity of the system is greater than the combined electromagnetic output of the entire observable universe.
Hadronic- and electromagnetic cores of air-showers observed by hybrid experiments at high mountains
High Energy Astrophysical Phenomena (astro-ph.HE)
2011/1/4
Characteristics of the high energy families (bundle of high energy e, gamma) and hadrons in the air-showers detected in the hybrid experiment together with emulsion chamber and AS-array at Mt.Chacalta...
Testing the No-Hair Theorem with Observations in the Electromagnetic Spectrum. III. Quasi-Periodic Variability
High Energy Astrophysical Phenomena (astro-ph.HE) General Relativity and Quantum Cosmology (gr-qc)
2010/12/24
According to the no-hair theorem, astrophysical black holes are uniquely described by their masses and spins. An observational test of the no-hair theorem can be performed by measuring at least three ...
Effects of the Electromagnetic Field on Five-dimensional Gravitational Collapse
Electromagnetic field Gravitational collapse Cosmological constant
2010/3/18
This paper investigates the five-dimensional(5D) spherically symmetric gravitational collapse with positive cosmological constant in the presence of an electromagnetic field. The junction conditions b...
