GBT Observations of SGR 1806-20 or SGR 1900+14 During Outburst

Abstract

We request in advance target-of-opportunity observations of the soft gamma repeater SGR 1806-20 or SGR 1900+14 to be triggered the next time either source goes into outburst, as determined by the Proportional Counter Array aboard NASA's Rossi X-ray Timing Explorer. The goal of the requested observations is to detect possible brief radio bursts that are temporally correlated with the high-energy outbursts. Such radio bursts are predicted in some models of magnetar emission, yet have never been searched for. The detection of such outbursts would be a major new discovery in magnetar science, and would provide new insight into the physics of ultra-highly magnetized neutron stars.
