Description Coordinated study of flare emission from Sgr A*, the closest supermassive black hole, reveals information about the hydrodynamics, energetics, and accretion behavior of matter within the innermost ten Schwarzschild radii. We propose to use the unique capability of Herschel-SPIRE and XMM in order to characterize flare emission simultaneously at many different wavelengths. These measurements will explore the nature of emission at the peak of the spectrum of Sgr A* and will determine the transition wavelength at which the variable emission becomes optically thin. In particular, we will test the prediction that there will be time delay between Xa??ray flares and the peak emission at micron wavelengths.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
