AN X-RAY STUDY ON N44: A REJUVENATED SUPER BUBBLE IN THE LMC

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 Xray brightest SB in the LMC, N44, is the besttarget to open new windows since a hint of cavity reheating as well as the hardXray emission can be seen by ASCA and ROSAT. We thus propose a observation onN44 with XMM. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
