论文摘要
Cygnus \,OB2区域,$ \ sim 3.5-5〜 \ text {myr} $ old,包含银河系中最重要的大型恒星之一。这样的恒星极大地有助于产生大规模软($ <2〜 \ text {kev} $)弥漫性X射线发射。我们还检测到了硬($> 3〜 \ text {kev} $)在Pulsar psr \,J2032+4127方向上分散X射线发射。圆环形的发射涵盖了$ \ 3'\ times 2'$类似喷气的结构。它在空间上与Fermi $γ$ -Ray源4FGL \,J2032.3+4127一致。我们建议硬弥漫性X射线发射是带有Pulsar PSR \,J2032+4127的脉冲星云,这是该地区过去核心爆炸SN爆炸的结果。
The Cygnus\,OB2 region, $\sim 3.5-5~\text{Myr}$ old, contains one of the most significant populations of massive stars of the Milky Way. Such stars substantially contribute to producing large scale soft ($<2~\text{keV}$) diffuse X-ray emission. We also detected hard ($>3~\text{keV}$) diffuse X-ray emission in the direction of the pulsar PSR\,J2032+4127. The torus-shaped emission spans a $\approx 3'\times 2'$ jet-like structure. It is spatially coincident with the Fermi $γ$-ray source 4FGL\,J2032.3+4127. We suggest that the hard diffuse X-ray emission is the pulsar wind nebula bearing the pulsar PSR\,J2032+4127, a consequence of a past core-collapse SN explosion in the region.
