Query: Revised Rates of Stellar Disruption in Galactic Nuclei   We compute rates of tidal disruption of stars by supermassive black holes in
galactic nuclei, using downwardly-revised black hole masses from the M-sigma
relation. In galaxies with steep nuclear density profiles, which dominate the
overall event rate, the disruption frequency varies inversely with assumed
black hole mass. We compute a total rate for non-dwarf galaxies that is about a
factor ten higher than in earlier studies. Disruption rates are predicted to be
highest in nucleated dwarf galaxies, assuming that such galaxies contain black
holes. Monitoring of a rich galaxy cluster for a few years could rule out the
existence of intermediate mass black holes in dwarf galaxies.
