Search for gravitational waves from low mass compact binary coalescence in 186 days of LIGO’s fifth science run

We report on a search for gravitational waves from coalescing compact binaries, of total mass between 2 and $35M_{\odot }$, 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 $1.4\times {10}^{-2}$, $7.3\times {10}^{-4}$ and $3.6\times {10}^{-3}{\mathrm{yr}}^{-1}{\mathrm{L}}_{10}^{-1}$, respectively, where ${\mathrm{L}}_{10}$ is ${10}^{10}$ times the blue solar luminosity.
