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

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
