Fast radio bursts and their gamma-ray or radio afterglows as Kerr-Newman black hole binaries

TL;DR

This paper proposes that fast radio bursts originate from the collapse of Kerr-Newman black hole magnetospheres, with potential gamma-ray or radio afterglows from KNBH mergers, aligning with observed FRB properties and gravitational wave events.

Contribution

It introduces a novel model linking FRBs to Kerr-Newman black hole magnetosphere collapse and predicts observable electromagnetic and gravitational wave signatures.

Findings

Model explains FRB timescales and radiation mechanisms

Kerr-Newman black hole mergers can produce afterglows

Predictions are testable with multi-wavelength and GW observations

Abstract

Fast radio bursts (FRBs) are radio transients lasting only about a few milliseconds. They seem to occur at cosmological distances. We propose that these events can be originated in the collapse of the magnetosphere of Kerr-Newman black holes (KNBHs). We show that the closed orbits of charged particles in the magnetosphere of these objects are unstable. After examining the dependencies on the specific charge of the particle and the spin and charge of the KNBH, we conclude that the resulting timescale and radiation mechanism fit well with the extant observations of FRBs. Furthermore, we argue that the merger of a KNBH binary is one of the plausible central engines for potential gamma-ray or radio afterglow following a certain FRBs, and can also account for gravitational wave (GW) events like GW 150914. Our model leads to predictions that can be tested by combined multi-wavelength electromagnetic and GW observations.
