Continuous gravitational wave detection to understand the generation mechanism of fast radio bursts

TL;DR

This paper explores a model where gravitational waves interacting with pulsar magnetospheres produce electromagnetic signals that could explain fast radio bursts, and discusses how gravitational wave detectors might validate this theory.

Contribution

It introduces the Gertsenshtein-Zel'dovich effect as a mechanism for FRB generation and assesses the detectability of associated gravitational waves with current detectors.

Findings

The GZ effect can produce EM radiation consistent with FRB observations.

Gravitational waves from pulsars could be detectable by existing detectors.

Detection of such waves could confirm the GZ model for FRBs.

Abstract

Since the unexpected discovery of fast radio bursts (FRBs), researchers have proposed varied theories and models to explain these phenomena. One such model that has recently been developed incorporates the so-called Gertsenshtein-Zel'dovich (GZ) effect, which states that when gravitational waves traverse a pulsar magnetosphere, a portion of the gravitational radiation is transformed into electromagnetic (EM) radiation. The observed properties of FRBs are consistent with the properties of this EM radiation, implying, remarkably, that the GZ effect can account for both repeating and non-repeating FRBs. If this model is correct, the pulsar's properties should not change over time, and it would continue to emit both EM dipole and gravitational quadrupole radiation for a long period of time. This article targets the gravitational radiation produced by the pulsar mechanism and shows that several proposed gravitational wave detectors can detect these gravitational waves. If such detections are performed in the future from the location of FRBs, it might validate the GZ process for FRB production and potentially rule out several other theories of FRB generation.
