|Title||Search for synchrotron x-ray SNRs as birthplaces of cosmic rays|
|Author||Dr Aya Bamba|
|Description||SNRs emitting synchrotron X-rays (SXSNR) accelerate cosmic rays up to a few hundreds TeV, though the number of them are still smaller to account for all the number of high energy cosmic rays in our Galaxy. Next subject would be to know how many SXSNRs are still unknown behind large absorption in previous observations, and to estimate the rate of cosmic rays in SNRs quantitatively. We selected SXSNR candidates from ASCA Galactic ridge survey and began to judge whether they are truly SXSNR or not with ASCA, Chandra, and Newton. Our observations will complete our SXSNR search and reveal us the critical clues about the subjects of cosmic ray acceleration.|

|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.
