Interaction of Gravitational Waves with Charged Particles

TL;DR

This paper explores how gravitational waves can transfer energy to charged particles, potentially causing wave attenuation and affecting the analysis of early universe gravitational wave data.

Contribution

It introduces the concept that charged particle clouds can absorb gravitational wave energy, a novel mechanism with implications for astrophysics.

Findings

Charged particles can absorb energy from gravitational waves.

Wave attenuation may occur in regions with charged particle clouds.

Implications for interpreting early universe gravitational wave signals.

Abstract

It is shown here that a cloud of charged particles could in principle absorb energy from gravitational waves (GWs) incident upon it, resulting in wave attenuation. This could in turn have implications for the interpretation of future data from early universe GWs.
