Quantum gravity & BH-NS binaries

TL;DR

This paper proposes that Black Hole-Neutron Star binaries can serve as natural astrophysical tests for quantum gravity effects, specifically through observable black-hole mass loss influenced by quantum spacetime non-commutativity.

Contribution

It introduces the idea that BH-NS binaries can be used to detect quantum gravity effects via enhanced black-hole mass loss due to non-commutative spacetime.

Findings

Black hole mass loss can be enhanced in BH-NS binaries due to quantum gravity effects.

Quantum spacetime non-commutativity introduces an additional length scale affecting observable phenomena.

BH-NS binaries are promising probes for testing quantum gravity in multi-messenger astronomy.

Abstract

We argue that the Black Hole-Neutron Star (BH-NS) binaries are the natural astrophysical probes of quantum gravity in the context of the new era of multi-messenger astronomy. In particular, we discuss the observable effect of enhanced black-hole mass loss in a BH-NS binary, due to the presence of an additional length scale tied to the intrinsic non-commutativity of quantum spacetime in quantum gravity.
