摘要
寻找宇宙射线(CRs)的起源是天文学中的一个根本问题。超新星遗迹(SNRs)的冲击波一直被认为是近 百万太子电子伏(太赫子电子伏)处于谱峰以下的 Galactic 射线的主要贡献者。是否是 SNRs 能效加速超过太赫子能级的粒子长期以来一直存在争议。本文报告了来自两个中年壳状 SNR、G150.34.5 和 -Cygni 的非常高能 射线辐射最高可达数百 TeV，观测数据来自大高原气射线观测站(LHAASO)。在这两个源中观察到两个(或三个)具有凸谱形状的不同形态/谱成分，其中低能成分的比例更广泛。虽然这些高能成分可能由强大的脉冲子星体驱动，但鉴于高能成分与分子云在相同距离上的 likely 关联，以及这些 SNRs 内部缺乏或不存在脉冲子星体风暴体(PWNe)，我们首次指出最高能辐射来源于原始太赫子能级 CRs 与云的碰撞。这些结果与该经典模型的预测一致，即在 SNR 演化自由膨胀阶段结束后加速的太赫子能级粒子可以照亮相邻的分子云(MCs)，从而产生强烈的 射线辐射。
