SNRs W28和W44:分子云中的旧cosmic ray加速器

SNRs W28 and W44: old cosmic ray accelerators in molecular clouds

V. N. Zirakashvili, V. S. Ptuskin

摘要:

用非线性扩散激波加速模型研究了老超新星遗迹W28和W44中的粒子加速。我们模拟了残余物的流体动力学演化、激波修正和加速粒子产生的流动不稳定性。与现有的无线电和伽马射线数据的比较。

英文摘要:

Nonlinear model of diffusive shock acceleration is used for investigation of the particle acceleration in old supernova remnants W28 and W44. We modeled the hydrodynamical evolution of the remnants, shock modification and streaming instability produced by accelerated particles. Comparison with available radio and gamma-ray data is given.
