Abstract:
We report first results from a multiwavelength campaign to measure the
simultaneous spectrum of Sgr A* from cm to mm wavelengths. The
observations confirm that the previously detected submm-excess is not
due to variability; the presence of an ultracompact component with a
size of a few Schwarzschild radii is inferred. In a VLA survey of
LINER galaxies, we found Sgr A*-like nuclei in one quarter of the
galaxies searched, suggesting a link between those low-power AGN and
the Galactic Center.
