Studies on the Quantum Transport Phenomena in and around Dense Astrophysical Objects

逆康普顿散射（光子-电子弹性散射）是最基本的反应之一，在天体物理学和宇宙学的量子输运现象中有着广泛的应用。例如，(1)星系团中电子的宇宙微波背景光子的逆康普顿散射导致光谱扭曲（Sunyaev-Zeldovich效应），(2)超新星遗迹的高能伽马射线的辐射机制。本课题通过解析和数值求解宇宙微波背景光子和电子的量子输运方程，对这两个问题进行了理论研究。

The inverse Compton scattering(the photon-electron elastic scattering) is one of the most fundamental reactions which have a variety of applications to the quantum transport phenomena in astrophysics and cosmology. They are, for example, (1) the inverse Compton scattering of cosmic microwave background photons from electrons in galaxy clusters which makes the distortion of the spectrum(the Sunyaev-Zeldovich effect), and (2) the radiation mechanism of high-energy gamma-rays from supernova remnants. In the present research project, we have made theoretical investigations on these two subjects by solving the quantum transport equation of the cosmic microwave background photons and electrons both analytically and numerically.
