The Fermi mission opened a new era for pulsar astronomy, detecting gamma-raypulsations from more than 60 pulsars, 30% of which are not seen at radiowavelengths. One of the most interesting Fermi pulsars is PSR J0357+32, aradio-quiet source standing out as the gamma-ray pulsar with the smallestspin-down luminosity (Erotvirgul1e33 erg/s) known so far. We observed PSR J0357+32with Chandra and we detected its X-ray counterpart, but we could not constrainits emission properties. Chandra data unveiled the existence of a huge (9 arcminlong) extended feature apparently protruding from the pulsar, with a peculiarphenomenology. We ask for a deep observation with XMM in order to assess thepulsar emission properties as well as the nature of the extended feature.

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.
