高能天体物理现象

摘要
背景：包含 Seyfert 和 starburst 成分的复合星系可能在从超大质量黑洞的几个史德瓦希半径到千秒尺度的喷流驱动的星系中产生广泛范围的高能（VHE；>100 GeV）伽马射线辐射。除了超新星遗迹，各种来源都被认为可以解释在复合星系上收集的数据，包括多信使 neutrinos 和超高能宇宙射线数据。目标：观测最近的复合性 Seyfert-starburst 星系（NGC 1068、Circinus 星系和 NGC 4945），以对这些系统中的宇宙射线 Population 提供约束。方法：分析 H.E.S.S. 观测数据，以搜索与 Fermi-LAT 检测到的 GeV 伽马射线信号相对应的 VHE 伽马射线，以及是否存在 VHE 范围内的潜在光谱分量。结果：在这些 H.E.S.S. 数据中未发现显著信号。对 VHE 伽马射线通量应用了上限，以约束涉及不同光谱分量的理论模型。
