11.4. Gravitational Waves

If GRBs are associated with NS²Ms then they will be associated with gravitational waves and low energy neutrinos. The spiraling in phase of a NS²M produces a clean chirping gravitational radiation signal. This signal is the prime target of LIGO [299] and VIRGO, the two [300] large interferometers that are build now in the USA and in Europe. The observational scheme of these detectors is heavily dependent on digging deeply into the noise. Kochaneck & Piran [301] suggested that a coincidence between a chirping gravitational radiation signal from a neutron star merger and a GRB could enhance greatly the statistical significance of the detection of the gravitational radiation signal. At the same time this will also verify the NS²M GRB model.
