  Coalescing binaries in distant galaxies are one of the most promising sources
of gravitational waves detectable by the LIGO project.$^{[1-5]}$ They are also
a copious source of neutrinos,$^{[1]}$ however these neutrino pulses are far
too weak to be detected on earth. Several years ago Eichler \etal$\,$$^{[6]}$
suggested that they are also sources of $\gamma$-ray bursts (GRBs). Recently it
was found$^{[7]}$ that GRBs are likely to be cosmological in origin, and
coalescing binary systems$^{[6,8-11]}$ are probably the most promising
cosmological sources. The current estimates of the burst and LIGO rates from a
cosmologically distributed population are based on the systems observed in our
galaxy.$^{[12-14]}$ These estimates are based on only three binarys so there
are large statistical uncertainties in the coalescence rate. If we accept the
cosmological/coalescing binary hypothesis for GRBs, then we get a more accurate
estimate of the rate at which binaries coalesce and hence of the predicted LIGO
signal. The association between GRBs and binaries can significantly improve the
performance of LIGO. The detection of gravitational radiation from a GRB source
not only confirms the coalescing binary model, but it will also provide
information on the geometry and energy generation mechanism of the burst.
