Scalar radiation emitted from a rotating source around a Reissner-Nordstrom black hole

TL;DR

This paper analytically and numerically studies scalar radiation from a rotating source orbiting a Reissner-Nordstrom black hole, exploring implications for the cosmic censorship conjecture in quantum contexts.

Contribution

It provides the first analytical calculations of scalar radiation emission rates in different frequency regimes around a Reissner-Nordstrom black hole, confirming numerical results.

Findings

Analytical emission rates match numerical calculations in low- and high-frequency regimes.

The study links scalar radiation emission to discussions on quantum cosmic censorship.

Results support the validity of the cosmic censorship conjecture in quantum scenarios.

Abstract

We investigate the radiation emitted from a scalar source in circular orbit around a Reissner-Nordstrom black hole. Particle and energy emission rates are analytically calculated in the low- and high-frequency regimes and shown to be in full agreement with a numerical calculation. Our investigation is connected with the recent discussion on the validity of the cosmic censorship conjecture in the quantum realm.
