摘要
伽马暴（GRBs）的最高能量伽马射线对其辐射机制具有重要意义。本文中，我们首次报道高海拔宇宙线观测站（LHAASO）从最亮的 GRB 221009A 探测到高达 13 TeV 的伽马射线。LHAASO-KM2A 探测器在触发后 230900s 期间记录到超过 140 个能量高于 3 TeV 的伽马射线。校正河外背景光（EBL）吸收后，伽马射线的内禀能谱可用幂律描述。如此硬谱对相对论电子用于数 TeV 以上余辉辐射的同步自康普顿（SSC）图景提出挑战。从一个测得红移 z=0.151 的源探测到高达 13 TeV 的伽马射线，暗示星系际空间的透明度高于此前预期。或者，可引入新物理，如洛伦兹不变性破坏（LIV）或甚高能（VHE）信号的轴子起源。
