TL;DR
This paper investigates scalar radiation from sources in circular orbits around Schwarzschild-de Sitter black holes, using quantum field theory to compare radiation power with that in Schwarzschild spacetime.
Contribution
It provides the first analysis of scalar synchrotron radiation in Schwarzschild-de Sitter spacetime within a quantum field theory framework.
Findings
Power of scalar radiation differs from Schwarzschild case
Quantum field theory approach applied at tree level
Results highlight effects of cosmological constant on radiation
Abstract
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 in curved spacetimes framework at tree level. We compare our results with the scalar synchrotron radiation in Schwarzschild spacetime.
