基于暗物质粒子探测卫星对伽玛暴高能辐射机制的研究

基于暗物质粒子探测卫星对5GeV-10TeV高能伽马光子的探测能力，我们将用于限制伽玛暴高能辐射机制。伽玛暴的高能辐射有多种可能的来源，按照辐射机制，有同步辐射和逆康普顿散射；按照辐射区域，有内激波区域、正反激波区、外激波区；按照辐射来源有高能电子和高能质子；对于逆康普顿散射，按照种子光子的来源，有各辐射区域同步辐射的光子、前身星的星光、可能的伴星的星光、红外背景光、微波背景辐射等。这些不同情形的组合，导致高能辐射来源的多样性。而不同的起源的特性将不一样，正是可以利用暗物质卫星和相关其它高能探测器进行甄别，从而确定伽玛暴高能辐射机制。

Based on the ability of 5GeV-10TeV detection onboard DAMPE satellite, we will constrain the high energy radiation mechanism of gamma-ray bursts (GRBs). There are a variety of origins for the GRB high energy photons. According to the radiation mechanism, there are synchrotron radiation and inverse Compton scattering. According to the radiation regions, there are internal shocks, reverse-forward shock and external shock. According to particle of the radiation, there are electrons and protons. According to the seed photons of the inverse Compton scattering, there are synchrotron radiation of different regions, stellar light of the progenitor star, stellar light of the possible companion star, infrared background and cosmic microwave background. Different combination of the cases above leads to the variety of the high energy radiation origins. While the properties of the different origin are different, the DAMPE satellite and other related high energy instruments can be used to distinguish them. Consequently, one can determine the radiation mechanism of the high energy photons of the GRBs.
