| Abstract | We recently discovered warm plasma having considerable extent in Galacticlatitude, rising from the Galactic plane at the locations of the Radio Arc andof the Sgr C thread and showing a sharp edge that correlates with the locationof the radio/mid-IR Galactic Center Lobe (GCL). We seek to investigate theorigin and energetic associated to this plasma. It might be associated to alarge scale inhomogeneous atmosphere present over the entire central molecularzone, related to continuous or episodic outflows of mass and energy from the GCregion. This would imply a large power to energise it. Alternatively, it couldbe, magnetically confined, warm X-ray emitting plasma filling the smaller scaleGCL. We ask for a mosaic of 15 observations of 25 ks (375 ks in total) to scan the GCL with XMM. |

| 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. |
