Abstract | The Cygnus Loop is one of the brightest, nearest (d sim 540pc), and mostextensively studied supernova remnants. There are numerous observationalindications that it originated from a core-collapse supernova whose progenitormass is sim 15,M _odot . Nevertheless, no neutron star related to the remnanthas yet been identified. A thorough {it Suzaku} XIS mapping of the Cygnus Loophas revealed a possible pulsar wind nebula (PWN) in the Loop. We propose a100,ks EPIC observation of the candidate PWN in order to determine whether ornot it is associated with the Cygnus Loop by measuring the neutron star propermotion and the column density to the nebula. This observation also will allow usto perform spectral mapping to characterize the PWN and constrain the neutron star pulse period. |

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. |
