摘要:

我们报告观测的伽马射线辐射的能量在100 TeV的能量区域从天鹅座地区在我们的银河系。在天鹅座OB1和OB2星协的方向上有两个显著的辐射源。基于它们的位置重合,我们将一个与脉冲星PSR J2032 + 4127相关联,另一个主要与脉冲星风星云PWN G75.2 + 0.1相关联,脉冲星远离其位于观测到的伽马射线发射质心周围的原始出生地。这项工作将促进对这些伽马射线源的粒子加速机制的进一步研究。

英文摘要:

We report observations of gamma-ray emissions with energies in the 100 TeV energy region from the Cygnus region in our Galaxy. Two sources are significantly detected in the directions of the Cygnus OB1 and OB2 associations. Based on their positional coincidences, we associate one with a pulsar PSR J2032+4127 and the other mainly with a pulsar wind nebula PWN G75.2+0.1 with the pulsar moving away from its original birthplace situated around the centroid of the observed gamma-ray emission. This work would stimulate further studies of particle acceleration mechanisms at these gamma-ray sources.
