Coordinated multi-wavelength observations of the Dark Mass at the Center of the Milky Way (15'+5')
The compact source SgrA* that can be associated with the massive
black hole at the center of the Milky Way shows a strong variability
from the radio to the X-ray wavelength domain.
Here report on the latest (May 2008, May 2007 and the years before)
simultaneous NIR/sub-millimeter/X-ray
observations using the NACO adaptive optics (AO) instrument at the
European Southern Observatory's Very Large Telescope,
the Australian Telescope Compact Array, the US mm-array CARMA
and other telescopes.We interpret the results
using a model in which spots in an accretion disk are on
relativistic orbits around SgrA*.
We discuss the energy release from the X-rays to the radio domain
in the framework of adiabatically expanding source components
and  consider the possibility of a jet or outflow from such a
central accretion disk.
