Multipole decomposition of the gravitational field of a point mass at the black hole horizon
João P. B. Brito, Atsushi Higuchi, Luís C. B. Crispino
The portion of the gravitational energy absorbed by the black hole due to the radial infall of a point mass is known to diverge at leading order in perturbation theory. This diverg…
Electromagnetic radiation from circular orbits in Schwarzschild--de Sitter spacetime
João P. B. Brito, Rafael P. Bernar, Luís C. B. Crispino
We investigate the electromagnetic radiation emitted by a charged particle orbiting a four-dimensional Schwarzschild--de Sitter black hole using a semiclassical approach. We calcul…
Larmor radiation as a witness to the Unruh effect
Atsushi Higuchi, George E. A. Matsas, Daniel A. T. Vanzella +5
We discuss the emission of radiation from general sources in quantum scalar, electromagnetic and gravitational fields using the Rindler coordinate frame, which is suitable for a un…
