Back reaction of the gravitational radiation on the metric of spacetime

TL;DR

This paper investigates how gravitational radiation from merging black holes affects spacetime, showing that intense gravitational waves can cause the disappearance of the accretion disc around the merged black holes.

Contribution

It introduces models demonstrating the impact of gravitational wave back reaction on the spacetime metric and accretion disc visibility during black hole mergers.

Findings

High energy density gravitational waves can eliminate the accretion disc.

Back reaction effects are significant near black hole mergers.

Models predict observable consequences of gravitational wave back reaction.

Abstract

The problem of back reaction of the gravitational radiation of the two merging black holes on the metric of the spacetime is investigated. It is shown for some models that large energy density of the gravitational waves close to the merger can lead to the disappearance of the visible accretion disc of the merged pair of black holes.
