摘要
本文描述了位于南极点的 IceCube 中微子望远镜对附近大质量恒星核心坍缩产生的 MeV 中微子爆发的响应。IceCube 于 2010 年 12 月建成，形成了一个由 5160 个光电倍增管组成的晶格，用于监测南极深冰中约 1 立方公里的体积，以寻找粒子诱发的光子。该望远镜设计用于探测能量大于 100 GeV 的中微子。由于冰温低于冰点，光电倍增管的暗噪声率特别低。因此，IceCube 也可以通过观察所有光电倍增管计数率在暗噪声之上的集体上升来探测大量的 MeV 中微子。凭借 2 毫秒的时间分辨率，IceCube 可以探测超新星中微子爆发时间演化的细微特征。对于银河系中心的超新星，其灵敏度与无本底的百万吨级超新星搜索实验相当。在银河系边缘 (30 kpc) 灵敏度降至 20 个标准差，在大麦哲伦云 (50 kpc) 降至 6 个标准差。IceCube 正在将来自潜在超新星的触发信号发送到超新星早期预警系统。讨论了其对中微子性质 (如中微子质量顺序) 的灵敏度，以及探测中子化爆发 (坍缩后不久由质子上的电子俘获释放出的电子中微子的短暂爆发) 的可能性。还研究了诸如夸克星或黑洞的形成以及冲击波的特征等诱人的信号，以说明 IceCube 的超新星探测能力。
