Scientific paper

We propose an EPIC observation of the recently discovered young PSR J2022+3842. Compared to other young pulsars in our Galaxy, J2022+3842 is exceptionally powerful and has the shortest spin period. An archival Chandra image has revealed a point source and a faint compact nebula with puzzling X-ray properties. The X-ray efficiencies of the pulsar and its PWN are orders of magnitude lower than one would expect for such a powerful pulsar. On the other hand, the object is still bright enough to allow a detailed study in X-rays. We will carry out a joint phase-resolved, multiwavelength analysis to better understand the radiatively-inefficient energy loss mechanism of this outstanding pulsar. We will also look for a large-scale X-ray emission from the PWN and the host SNR.
