Non-detection of pulsed radio emission from magnetar Swift J1834.9-0846: constraint on the fundamental plane of magnetar radio emission

Abstract

The magnetar Swift J1834.9-0846 is observed using Nanshan 25 meter radio telescope. No pulsed radio emission is detected. The upper limit on pulsed radio emission from this source is 0.5 mJy. According to the fundamental plane for radio magnetars, this source should have radio emission. Therefore, our results put constraints on the existence of a fundamental plane of magnetar radio emission. We argue that a magnetar's ability to emit radio emission may have little to do with the spin down luminosity and it is related to the magnetar X-ray luminosity. The only necessary condition is a relatively low X-ray luminosity.
