Abstract Supergiant shells with diameters approaching 1000 pc may break through thegaseous disk of their host galaxy and inject chemically enriched hot gas intothe galactic halo. Thus they play an important role in the global structureand evolution of the ISM. We have been conducting a multi-wavelength study ofthe supergiant shells in the Large Magellanic Cloud in order to understand theirphysical conditions and how they contribute to the hot ionized gas component ofthe ISM. We request XMM observations of the supergiant shell LMC1, which showsan HI hole in a coherent ionized gas shell, in sharp contrast to the supergiantshell LMC2 observed by XMM in AO1. The XMM observations will be supplements byoptical and radio data for a full analysis of the physical structure of LMC1.

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.
