Scientific paper

The young pulsar PSR J1846-0258 was long thought to be exclusively rotation-powered. Our discovery of magnetar-like emission from this source makes it the only known example of a rotation-powered pulsar/magnetar transition object. Following its outburst, our Rossi X-ray Timing Explorer (RXTE) observations revealed that the pulsar's pulsed flux returned to its quiescent value. However, with our background dominated RXTE observations we cannot determine whether the spectrum and total flux, and hence pulsed fraction, have as well. PSR J1846-0258 is the only source that exhibits both magnetar-like emission and a bright and variable pulsar wind nebula (PWN). The requested observations will help constrain the nature of the interesting variability observed in this PWN.
