Description
Summary:We report on a search for gravitational waves from coalescing compact binaries, of total mass between 2 and 35M[subscript ⊙], using LIGO observations between November 14, 2006 and May 18, 2007. No gravitational-wave signals were detected. We report upper limits on the rate of compact binary coalescence as a function of total mass. The LIGO cumulative 90%-confidence rate upper limits of the binary coalescence of neutron stars, black holes and black hole-neutron star systems are 1.4×10[superscript -2], 7.3×10[superscript -4] and 3.6×10[superscript -3]  yr[superscript -1] L[subscript 10][superscript -1], respectively, where L[subscript 10] is 10[superscript 10] times the blue solar luminosity.
