| Description | The SNR-cloud interaction gives significant effects on the X-ray spectra; the cloud evaporation would enhance the thin thermal component, while the SNR-cloud interaction may trigger high energy particle acceleration and produce non-thermal X-rays, and probably GeV gamma-rays. We propose to untangle of these two processes with the XMM-Newton observations on the interaction and non-interaction regions in the same SNR W28. The east shell of W28 consists of two knots; the northern knot would be in pre-interaction phase, whereas the southern one has just interacted with molecular clouds. The primary objective is to search for non-thermal X-ray emissions from these knots, that is to say, the high energy cosmic rays from cloud interaction SNRs. |

| 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. |
