|Title||A survey of non-thermal shell SNR candidates|
|Author||Prof Rino Bandiera|
|Description||The investigation of the general properties of non-thermal X-ray shell SNRs, of which SNvirgul1006 is the prototype, is essential to understand how electrons are accelerated in SNR shocks and in general the origin of cosmic rays. Unfortunately, this class of SNRs is composed by too few members: we then propose an XMM large scale program aimed at the discovery of new such objects. We introduce a new selection criterion: the underlying idea is to select SNRs expanding in a lower density medium, i.e. with a lower thermal X-ray emission, that usually outshines the non-thermal one. We have selected the 9 best candidates, still not studied or poorly studied in X rays.|

|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.
