Detecting an Extreme Pulsar Tail in X-rays

We propose XMM observations of a pulsar wind nebula (PWN) associated with theFrying Pan supernova remnant (SNR) G315.90.0. Powered by the energetic pulsarJ14375959 with a space velocity over 1000km/s, this remarkable PWN has aphysical extent over 20pc in radio, the longest pulsar tail ever observed. It isthe only known bow shock PWN with the parent SNR detected. This reveals theentire history of the system and allows us to determine many important physicalparameters that are not easily accessible in other bow shocks. Detecting anXray counterpart will complement our radio study to offer a complete physicalpicture of the system. This will advance our understanding of pulsar windelectrodynamics and relativistic shock physics. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
