Search for gravitational waves from supernovae and long GRBs
  We report on evidence for black hole spindown in the light curves of the
BATSE catalogue of 1491 long GRBs by application of matched filtering. This
observation points to a strong interaction of the black hole with surrounding
high density matter at the ISCO, inducing non-axisymmetric instabilities
sustained by cooling in gravitational wave emission. Opportunities for
LIGO-Virgo and the recently funded KAGRA experiments are highlighted, for long
GRBs with and without supernovae and for hyper-energetic core-collapse
supernovae within a distance of about 35 Mpc in the Local Universe.
