Abstract	Many astrophysical sources and cataclysmic phenomena are expected to produce gravitational waves and high-energy cosmic radiation in our Universe, in the form of photons, hadrons and presumably also neutrinos. Both gravitational waves (GW) and high-energy neutrinos (HEN) can escape very dense media and travel unabsorbed over cosmological distances, carrying information from the innermost regions of the astrophysical sources. Requiring consistency between GW and HEN detection channels enables new searches and a detection would yield significant additional information about the common source. We significant performed the first triggered analysis by combining GW data from the LIGO and Virgo interferometers around the time of neutrino triggers revealed from ANTARES neutrino telescope. No evidence for coincident events was found. We place a lower limit on the distance to GW sources associated with every HEN trigger. We are able to rule out the existence of coalescing binary neutron star systems and black hole-neutron star systems up to distances that are typically 5 Mpc and 10 Mpc, respectively. For generic waveforms, given certain assumptions, typical distance limits can be as high as 17 Mpc.
