基于DAMPE的河内伽马射线源物理过程研究

银河伽马射线源主要包括脉冲星及其风云、超新星遗迹等，是研究极端物理情况下高能粒子加速、传播和辐射、动力学演化等一系列高能物理过程的重要天体。基于暗物质粒子探测卫星（DAMPE）的观测，结合Fermi LAT及其它探测器的观测结果，本项目拟开展脉冲星及其风云（PWNe）、超新星遗迹（SNRs）相关物理过程的研究，主要包括（1）脉冲星及SNRs的观测，给出脉冲星和SNRs在能量大于1 GeV能区详细的辐射特性；（2）脉冲星、PWNe和SNRs中所发生的高能物理过程；（3）银河致密天体对宇宙线正电子/电子的贡献。

Pulsars, pulsar wind nebulae (PWNe), and supernova remnants (SNRs) are the major gamma-ray sources in our Galaxy, which play important roles to help us to understand the high energy physical processes such as particle acceleration and radiation mechanism, dynamical evolution, and particle propagation. In this project, based on the observation of the Dark Matter Particle Explorer (DAMPE), and combined with the results obtained from Fermi LAT, HESS and other satellites, we will study the high energy physical process of pulsars, PWNe and SNRs, and mainly focus on (1) observations of pulsars and SNRs; (2) high energy physics in pulsars, PWNe, and SNRs; and (3) the contributions of Galactic compact objects to the cosmic positrons/electrons.
