Gravitational Waves and GRBs from Tidal Disruption of Stars in the Center of Galaxies

TL;DR

This paper explores the hypothesis that gamma-ray bursts originate from stars being tidally disrupted by supermassive black holes in galactic centers, and discusses how gravitational wave detectors could test this idea.

Contribution

It proposes a novel link between GRBs and tidal disruption events by supermassive black holes, suggesting gravitational wave detection as a testing method.

Findings

Supermassive black holes are common in galaxy centers.

GRBs may be caused by stellar tidal disruptions.

Gravitational wave detectors like AURIGA could verify this hypothesis.

Abstract

Recent measurements of the Chandra satellite have shown that a supermassive black hole of $M = 2.6 \times 10^{6} M_{\odot}$ is located in the Galactic Center; it seems probable that, from other observations, this fact is common in the majority of galaxies. On the other hand, GRB explosions are typical phenomenon linked to the galactic dynamics. In the present paper we discuss the possibility that GRBs are tidal disruption of stars by supermassive black holes located in the center of galaxies. This conjecture can be tested by a gravitational wave detector of the class of AURIGA.
