Electromagnetic phenomena around black holes

TL;DR

This paper explores how gravitational waves from black hole mergers can convert into electromagnetic signals within magnetic fields generated by charged black holes, highlighting a potential electromagnetic counterpart to gravitational wave events.

Contribution

It introduces a model where electromagnetic phenomena around black holes arise from gravitational wave interactions in magnetic fields created by charged black holes, a novel approach.

Findings

Electromagnetic radiation can be produced from gravitational waves near black holes.

Charged black holes generate magnetic fields influencing electromagnetic phenomena.

The process depends on plasma properties and black hole charge dynamics.

Abstract

Transition of gravitational waves, produced in the process of coalescence of black hole binaries, into electromagnetic radiation in magnetic field is discussed. The magnetic field is assumed to be created by rotating electrically charged black holes. The process of electric charging of black holes due to different mobilities of protons and electrons in the surrounding plasma is described.
