Radio emission from magnetars

We discuss properties of the expected radio emission from soft gamma-ray repeaters (SGRs) during their bursting activity in the framework of the model of Thompson, Lyutikov, & Kulkarni, in which the high-energy emission is powered by the dissipation of superstrong magnetic fields in the magnetospheres through reconnection-type events. Drawing on analogies with solar flares, we predict that coherent radio emission resembling solar type III radio bursts may be emitted in SGRs during X-ray bursts. The radio emission should have correlated pulse profiles with X-rays, a narrowband-type radio spectrum with Deltanu less than or equal to nu, with the typical frequency nu greater than or equal to 10 GHz, and, possibly, a drifting central frequency. We encourage sensitive radio observations of SGRs during the bursting activity.
