Temporal variations in space-time and progenitors of gamma ray burst and millisecond pulsars

TL;DR

This paper demonstrates that dynamic space-time metrics, especially during black hole and neutron star mergers, can generate electromagnetic radiation, potentially explaining gamma ray bursts and millisecond pulsars.

Contribution

It introduces a model linking time-varying space-time metrics to electromagnetic emissions, highlighting progenitors of gamma ray bursts and pulsars.

Findings

Large temporal metric variations can produce gamma ray bursts.

Black hole and neutron star coalescences are potential progenitors.

Post-Newtonian approximation effectively models these phenomena.

Abstract

A time varying space-time metric is shown to be a source of electromagnetic radiation. The post-Newtonian approximation is used as a realistic model of the connection between the space-time metric and a time varying gravitational potential. Large temporal variations in the metric from the coalescence of colliding black holes and neutron stars are shown to be possible progenitors of gamma ray burst and millisecond pulsars.
