Covering the central 20*2.5deg2 of the Milky Way disc with 20ks XMM exposureswill allow us to measure the flows of hot baryons emerging from the energeticactivity in the disc, to detail their impact on the surroundings and to connectthe sources in the disc with the base of the Galactic outflow. By connecting therequested XMM scan with the shallow all sky eROSITA survey, we will determinewhether the activity in the Galactic disc is important for feeding andsustaining the Galactic corona. This study will provide us with an excellentarchetype for advancing our understanding of galaxy evolution theory in aMilky-Way-class galaxy. This project will produce a legacy dataset that will beused in the future for multiple purposes, including multi-wavelength and time-domain investigations.

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.
