Analog Particle Production Model for General Classes of Taub-NUT Black Holes

TL;DR

This paper establishes a novel correspondence between Hawking radiation from Taub-NUT black holes and the particle production by accelerated mirrors in flat spacetime, revealing how black hole parameters influence radiation spectra.

Contribution

It introduces a new analogy linking black hole Hawking radiation to mirror-induced particle production, extending to rotating and charged Taub-NUT black holes.

Findings

Radiation spectra are thermal at late times.

Particle production is suppressed by the NUT parameter.

Explicit spectra computed for Kerr-Newman Taub-NUT and extremal cases.

Abstract

We derive a correspondence between the Hawking radiation spectra emitted from general classes of Taub-NUT black holes with that induced by the relativistic motion of an accelerated Dirichlet boundary condition (i.e.\ a perfectly reflecting mirror) in (1+1)-dimensional flat spacetime. We demonstrate that the particle and energy spectra is thermal at late-times and that particle production is suppressed by the NUT parameter. We also compute the radiation spectrum in the rotating, electrically charged (Kerr-Newman) Taub-NUT scenario, and the extremal case, showing explicitly how these parameters affect the outgoing particle and energy fluxes.
