Interaction of the gravitational Hawking radiation and a static point mass

João P. B. Brito, Atsushi Higuchi, Luís C. B. Crispino

We study the interaction of a stress-energy tensor describing a static point mass supported by a string outside a Schwarzschild black hole with the gravitons of the Hawking radiati…

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…

Nonminimally coupled scalar field in Schwarzschild--de Sitter spacetime: Geodesic synchrotron radiation

João P. B. Brito, Rafael P. Bernar, Luís C. B. Crispino

We analyze the scalar radiation emitted by a source interacting with a nonminimally coupled scalar field in four-dimensional Schwarzschild--de Sitter spacetime. We obtain the emiss…

Semiclassical bremsstrahlung from a charge radially falling into a Schwarzschild black hole

João P. B. Brito, Rafael P. Bernar, Atsushi Higuchi +1

A semiclassical investigation of the electromagnetic radiation emitted by a charged particle in a radially freely falling motion in Schwarzschild spacetime is carried out. We use q…

Gravitational bremsstrahlung and the Fulling-Davies-Unruh thermal bath

João P. B. Brito, Luís C. B. Crispino, Atsushi Higuchi

The electromagnetic radiation emitted by an accelerated charged particle can be described theoretically as the interaction of the charge with the so-called Fulling-Davies-Unruh the…

Radiation emitted by a source orbiting a Schwarzschild--anti--de Sitter black hole

J. P. B. Brito, R. P. Bernar, L. C. B. Crispino

We study the scalar radiation emitted by a source orbiting a Schwarzschild--anti--de Sitter black hole in circular geodesics. We obtain the emitted power using quantum field theory…

Synchrotron geodesic radiation in Schwarzschild-de Sitter spacetime

João P. B. Brito, Rafael P. Bernar, Luís C. B. Crispino

We analyze the scalar radiation emitted by a source in geodesic circular orbits around a Schwarzschild-de Sitter black hole. We obtain the emitted power using quantum field theory…
