Radio transients from neutron stars binary mergers

TL;DR

This paper explores the potential for detecting radio bursts from neutron star mergers associated with short gamma-ray bursts, emphasizing low-frequency observations with instruments like LOFAR to identify these events up to redshift 0.3.

Contribution

It proposes a method to detect radio transients from neutron star mergers using low-frequency radio telescopes, highlighting the advantages of low-frequency bands and LOFAR's capabilities.

Findings

LOFAR can detect radio bursts from neutron star mergers up to z~0.3.

Estimated detection rate is approximately 25 events per year.

Low-frequency radio observations are advantageous due to intergalactic medium effects.

Abstract

We discuss possible radio bursts which can be generated during binary neutron stars mergers associated with short gamma-ray bursts. Low-frequency radio band appear to be advantageous due to the time delay of a radio signal propagating in the intergalactic medium, which makes it possible to use short gamma-ray burst alerts to search for specific regions on the sky by low-frequency radio instruments, especially LOFAR. The LOFAR sensitivity will allow significant detection of such bursts up to redshifts z~0.3 with a rate of ~25 events per year.
