Constraining coherent low frequency radio flares from compact binary mergers [HEAP]

http://arxiv.org/abs/1905.02509


The presence and detectability of coherent radio emission from compact binary mergers (containing at least one neutron star) remains poorly constrained due to large uncertainties in the models. These compact binary mergers may initially be detected by a Short Gamma-ray Burst (SGRB) or via their gravitational wave emission. Several radio facilities have developed rapid response modes enabling them to trigger on these events and search for this emission. This paper uses the current deepest constraints on this emission, for GRB 150424A from the Murchison Widefield Array. Following on from this, we consider a magnetar remnant formed via a general population of neutron star mergers to demonstrate that all the different potential emission mechanisms can be observed or very tightly constrained by the complimentary strategies used by the current generation of radio telescopes.
