Surveying the Galactic Plane with XMM

We propose an ambitious longterm programme to survey the inner regionsof the Galaxy using XMM, which in AO1 involves the mapping of a 12 degree strip of the Galactic plane centred on l25.5. The XMM observations will surpass current Xray data by > 100 in sensitivity whilst providing excellent spatial and spectral resolution. Complementary radio, optical and nearIR imaging will provide a key asset for the interpretation of the new data.This survey will lead to major advances in our understanding of star formation, stellar coronae, SNRs, the hot ISM and accretion processes. We waive all proprietary data rights in order to ensure the widest possible community participation in this project. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
