摘要:

MGRO J2019+37区域是天空中TeV能量最亮的源之一。它在2年HAWC目录中被发现为2HWC J2019+367,在这里我们使用HAWC的数据对该地区进行了详细的研究。该分析将该地区分为两个来源:HAWC J2019+368和HAWC J2016+371。我们将HAWC J2016+371与演化的超新星遗迹CTB 87联系在一起,尽管它在这项分析中的重要性很低,因此无法在此时进行详细的研究。对HAWC J2019+368的形貌(包括可能的能量依赖形貌)和光谱的研究是这项工作的重点。我们将HAWC J2019+368与PSR J2021+3651及其X射线脉冲星风星云蜻蜓星云联系在一起。模拟HAWC和朱雀测量的光谱揭示了一个$\sim$ 7 kyr脉冲星和星云系统,产生所观察到的X射线和$γ$射线能量的发射。

英文摘要:

The MGRO J2019+37 region is one of the brightest sources in the sky at TeV energies. It was detected in the 2 year HAWC catalog as 2HWC J2019+367 and here we present a detailed study of this region using data from HAWC. This analysis resolves the region into two sources: HAWC J2019+368 and HAWC J2016+371. We associate HAWC J2016+371 with the evolved supernova remnant CTB 87, although its low significance in this analysis prevents a detailed study at this time. An investigation of the morphology (including possible energy dependent morphology) and spectrum for HAWC J2019+368 is the focus of this work. We associate HAWC J2019+368 with PSR J2021+3651 and its X-ray pulsar wind nebula, the Dragonfly nebula. Modeling the spectrum measured by HAWC and Suzaku reveals a $\sim$7 kyr pulsar and nebula system producing the observed emission at X-ray and $γ$-ray energies.
