引力波干涉仪与高能中微子望远镜的符合

Coincidences between Gravitational Wave Interferometers and High Energy Neutrino Telescopes

Thierry Pradier

摘要:

引力波(GW)源和高能中微子(HE)发射源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吸积,并在相对论喷流中喷出,中微子被认为是在那里产生的。这两个信使与周围物质的相互作用很弱,因此直接指向为这些排放提供动力的发动机的心脏。GW干涉仪(例如Virgo)和HE中微子望远镜(例如Ancanton)之间的巧合将对宇宙中最强大物体的物理学提供独特的见解。分析了GW/HE中微子符合的可能性、可观测性和可探测性。

英文摘要:

Sources of gravitational waves (GW) and emitters of high energy (HE) neutrinos 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 neutrino 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 neutrino coincidences are analysed.
