Scientific paper

The pulsar wind bow shock nebula surrounding PSR B1853+01, embedded within the SNR W44, is the oldest known wind nebula associated with an active pulsar. Chandra observations have shown that the X-ray morphology is that of an asymmetric nebula trailing behind the pulsar's apparent motion direction, with a smaller extent than the radio. A recent, deep Chandra image suggests an extended region of emission preceding the pulsar. The verification of the nature of this emission as nonthermal and associated with the pulsar has strong implications for our understanding of pulsar bow shock nebulae. We propose a 75 ks EPIC observation of this intriguing object, exploiting XMM-Newton's unique surface brightness sensitivity above 3 keV to establish the nature of the emission.
