PSR J2021+4026 is the second brightest radio-quiet gamma-ray pulsar which issuggested to be the long-sought compact object associated with the supernovaremnant gamma-Cygni. Its radio-quietness and its multiwavelength propertiessuggest its nature to be similar to a well-known pulsar: Geminga. In order totightly constrain the nature of its X-ray counterpart, we propose a deepXMM-Newton observation with an aim to search for its X-ray pulsations andperform a detailed spectro-imaging analysis.

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.
