Super bubbles (SBs) are the complex of multiple SN explosions and strong stellarwinds, hence would be a key cite of high energy activity such as hightemperature plasma and particle acceleration. However, no observational evidencefor particle acceleration and/or limited information of high temperature plasmahas only been obtained due to the limited energy band and a poor statistics ofprevious observations. The X-ray brightest SB in the LMC, N44, is the besttarget to open new windows since a hint of cavity re-heating as well as the hardX-ray emission can be seen by ASCA and ROSAT. We thus propose a observation onN44 with XMM.

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.
