引力波（GW）的来源和高能中微子（HE ν）的发射器都涉及以相对论速度运动的致密物体和物质。GW发射需要偏离球形对称，如果物质团块在黑洞或中子星周围被吸积，并以相对论性喷流的形式喷射出来，就会出现这种情况，而中微子被认为是在相对论性喷流中产生的。这两种信使与周围物质的相互作用都很弱，因此直接指向驱动这些排放物的发动机的核心。GW干涉仪（如处女座）和HE ν望远镜（如ANTARES）之间的巧合将为宇宙中最强大物体的物理学提供独特的见解。分析了这种GW/HE重合的可能性、可观测性和可探测性。
Sources of gravitational waves (GW) and emitters of high energy neutrinos (HE ν) both involve compact objects and matter moving at relativistic speeds. GW emission requires a departure from spherical symmetry, which is the case if clumps of matter are accreted around black holes or neutron stars, and ejected in relativistic jets, where neutrinos are believed to be produced. Both messengers interact weakly with the surrounding matter, hence point directly to the heart of the engines that power these emissions. Coincidences between GW interferometers (e.g. VIRGO) and HE ν telescopes (e.g. ANTARES) would then give a unique insight on the physics of the most powerful objects in the Universe. The possibility, observability and detectability for such GW/HE ν coincidences are analysed.
