High Energy Astrophysics with Emphasis on Particle Acceleration and Nonthermal Radiation Processes

在不同波长观测到的各种天体中，已知会产生高能粒子。这些粒子必须以某种方式加速。一种方法是用震源某处爆炸产生的冲击波来加速它们。关于扩散激波加速度的理论研究相当多。该理论现在可以在一定程度上用于模拟现实天体物理条件下的非热粒子分布。该研究项目将重点关注太阳粒子的加速、活动星系核、中子星和超新星的吸积。这些模型的预测结果将与地面和卫星观测结果进行比较。

Very high energy particles are known to be produced in various astronomical objects observed at different wavelengths. These particles must be accelerated in some way. One way is to accelerate them with a shock wave from some explosion somewhere in the source. There has been considerable theoretical research done on diffusive shock acceleration. The theory can now be used with some confidence to model nonthermal particle distributions in realistic astrophysical conditions. The research program will focus on the acceleration of particles in the Sun, active galactic nuclei, accreting neutron stars, and supernovae. The predictions of the models will be compared with ground-based and satellite-based observations.
