Spp we use matched filtering and define “no detection”: S/N<1
ConclusionsConclusionsGRB-SNe from rotating black holes have long durations (gamma0=1e4), small true
GRB-energies (gamma1=1e-4) and an true event rate of 1 per year in D=100Mpc
Durations of tens of seconds correspond to the lifetime of rapid spin of the black hole (gamma0[theory]=gamma0[observation]). Most of black hole spin-energy is dissipated in the event horizon.
GRB-SNe produce 4e53 erg in gravitational radiation via a causal spin-connection between the black hole and a surrounding torus in suspended accretion (gamma2=0.1)
The true GRB-energies represent a small fraction of black hole-spin energy, released through an open tube with finite horizon angle (gamma1[theory]=gamma1[observation])
Matched filtering gives (formally) rise to a current LIGO sensitivity range of 1Mpc, and a (formal) upper bound of 25 Solar masses in GRB 030329
The sensitivity range of Adv LIGO using matched filtering is 100Mpc
Correlation between two detectors may apply to searches for individual events, as well as searches for the contribution of GRB-SNe to the stochastic background radiation in gravitational waves (Omega-B=6e-8)
Opportunity: gravitational radiation from hypernovae: LIGO/VIRGO detections coincident (in position on the sky) with the expected wide-angle optical emissions from an associated supernova and non-coincident with the associated GRB-emissions
