HOT GAS IN AND AROUND THE SUPERGIANT SHELL LMC-2

Supergiant shells with diameters approaching 1000 pc may break through thegaseous disk of their host galaxy, and transfer energy and mass into thegalactic halo. The Large Magellanic Cloud contains several supergiant shells,among which LMC2 has the most spectacular filamentary shell structure and thebrightest diffuse Xray emission. The Xray emission exists within the opticalshell boundary and extends beyond the southern shell rim. We propose to use theXMMNewton EPIC cameras to map LMC2 and its southern extension in order to studythe physical structure of LMC2 and the role it plays in the global structure ofthe interstellar medium. This program was awarded time in AO1, but virgul60% of theobservations were corrupted by high background. We request makeup time to complete our program. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
