Feedback by Massive Black Holes in Dwarf Galaxies
  Could there be intermediate mass black holes in essentially all old dwarf
galaxies? I argue that current observations of Active Galactic Nuclei in dwarfs
allow such a radical hypothesis which provides early feedback and potentially
provides a unifying explanation for many if not all of the apparent dwarf
galaxy anomalies, such as the abundance, core-cusp, "too big to fail",
ultra-faint and baryon-fraction issues. I describe the supporting arguments,
which are largely circumstantial in nature, and discuss a number of tests.
There is no strong motivation for modifying the nature of cold dark matter in
order to explain any of the dwarf galaxy "problems".
