摘要
MGRO J2019+37 区域是 TeV 能段天空中最亮的源之一。它在 HAWC 两年星表中被探测为 2HWC J2019+367，此处我们利用 HAWC 数据对该区域给出详细研究。该分析将区域解析为两个源：HAWC J2019+368 与 HAWC J2016+371。我们将 HAWC J2016+371 与演化中的超新星遗迹 CTB 87 相关联，尽管其在本分析中的低显著性使目前无法详细研究。对 HAWC J2019+368 形态（含可能的能量依赖形态）与能谱的探究是本文重点。我们将 HAWC J2019+368 与 PSR J2021+3651 及其 X 射线脉冲星风云——蜻蜓星云相关联。对 HAWC 与 Suzaku 所测能谱的建模揭示了一个约 7 kyr 的脉冲星与星云系统，产生了观测到的 X 射线与 射线能段辐射。
