Abstract Coordinated study of flare emission from Sgr A*, the closest supermassive blackhole, reveals information about the hydrodynamics, energetics, and accretionbehavior of matter within the innermost ten Schwarzschild radii. We propose touse the unique capability of Herschel/SPIRE and XMM in order to characterizeflare emission simultaneously at many different wavelengths. These measurementswill explore the nature of emission at the peak of the spectrum of Sgr A* andwill determine the transition wavelength at which the variable emission becomesoptically thin. In particular, we will test the prediction that there will betime delay between Xa??ray flares and the peak emission at micron wavelengths.

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.
