中微子望远镜阵列(NTA)--观测天文学$ν_τ$源

Neutrino Telescope Array (NTA) - Towards Survey of Astronomical $ν_τ$ Sources

George W. -S. Hou

摘要:

掠地$ν_τ$方法允许同时进行巨大的目标质量和检测体积。部分受IceCube PeV天体中微子事件的推动,计划中的NTA天文台有三个站点观测夏威夷岛上的莫纳罗亚山、莫纳克亚山和华拉莱山周围的气团,加上一个位于中心的站点观测较低的夜空。对PeV-EeV中微子进行切伦科夫荧光立体观测,可以获得与$> 100$ km $^3$水相当的灵敏度和$< 0.2^\circ$的指向精度。根据Ashra-1的经验进行设计,并以明确发现和识别天文学$ν_τ$源为目标,正在形成一种新的国际合作。

英文摘要:

The Earth-skimming $ν_τ$ method allows for huge target mass and detection volume simultaneously. In part motivated by IceCube PeV astro-neutrino events, the planned NTA observatory has three site stations watching the air mass surrounded by Mauna Loa, Mauna Kea, and Hualalai on Hawaii Island, plus a site station at the center watching the lower night sky. Sensitivities equivalent to $> 100$ km$^3$ water and pointing accuracy of $< 0.2^\circ$ can be achieved with Cherenkov-fluorescence stereoscopic observation for PeV-EeV neutrinos that is almost background-free. With design based on experience from Ashra-1 and the goal of clear discovery and identification of astronomical $ν_τ$ sources, a new international collaboration is being formed.
