半人马座A和银河系中心UHE中微子的LUNASKA实验观测极限
LUNASKA Experiment Observational Limits on UHE Neutrinos from Centaurus A and the Galactic Center
摘要:
本文首次给出了银河系中心和最近的活动星系核半人马座A超高能中微子流的观测极限。这些结果是基于我们在澳大利亚望远镜紧凑阵列(ATCA)的“使用平方公里阵列的月球UHE中微子天体物理学”(LUNASKA)项目实验。我们还推导出限制以前的实验和比较这些限制与预期的加速和超重暗物质模型的起源UHE宇宙射线。
英文摘要:
We present the first observational limits to the ultra-high energy (UHE) neutrino flux from the Galactic Center, and from Centaurus A which is the nearest active galactic nucleus (AGN). These results are based on our "Lunar UHE Neutrino Astrophysics using the Square Kilometer Array" (LUNASKA) project experiments at the Australia Telescope Compact Array (ATCA). We also derive limits for the previous experiments and compare these limits with expectations for acceleration and super-heavy dark matter models of the origin of UHE cosmic rays.
