Description Thermal-composite Supernova Remnants (SNRs) are a mystery. These remnants
present the spectral features of thermal-dominated SNRs and the morphology of
centrally-peaked composite SNRs. W44 is the perfect example of such SNR. Its
morphology remains a puzzle despite previous observations. The proposed 30 ks
observation will help solve this puzzle by mapping temperature and abundance
variations and comparing them to theoretical predictions. Both an X-ray and
radio synchrotron nebula are detected around the radio pulsar associated with
W44. This observation will spatially resolve the region of emission, compare it
to the existing high-resolution radio map, use spectral information to
characterize the nebula and maybe discover X-ray pulsations at the known radio
Publication No observations found associated with the current proposal

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
