Query: Electromagnetic priors for black hole spindown in searches for
  gravitational-waves from supernovae and long GRBs   Some core-collapse supernovae appear to be hyper-energetic, and a subset of
these are aspherical and associated with long GRBs. We use observations of
electromagnetic emission from core-collapse supernovae and GRBs to impose
constraints on their free energy source as a prior to searches for their
gravitational wave emission. We review these events based on a finite
efficiency for the conversion of spin energy to magnetic winds powering
supernovae. We find that some of the hyper-energetic events cannot be powered
by the spindown of rapidly rotating proto-neutron stars by virtue of their
limited rotational energy. They can, instead, be produced by the spindown of
black holes providing a distinct prospect for gravitational-wave emission of
interest to LIGO, Virgo, and the LCGT.
