"Nearby Active Galactic Nuclei seen with Keck Telescope Adaptive Optics"

Adaptive optics corrects for blurring due to turbulence in the
earth's atmosphere, so that under some circulstances telescopes on
the ground can "see" as clearly as if they were in space.  This talk
will begin with an overview of adaptive optics capabilities on the
current generation of 8-10 meter ground-based telescopes.  The talk
will then describe the use of adaptive optics on the Keck Telescope
to study the cores of nearby active galactic nuclei, which contain
supermassive black holes.
