论文摘要
快速模式磁性水力动力学（MHD）压缩波的传播在银河系中心的传播带有多磁缸。从细胞核弹出的MHD波反射并沿着磁场引导，表现出垂直拉伸的前部。无线电线和非热细丝的解释是由于SGR A $^*$或多个超新星零星活动驱动的波浪的切向观点。在后一种情况下，螺纹可能是在细胞核中爆炸的旧SNR的极端变形文物。
Propagation of fast-mode magnetohydrodynamic (MHD) compression waves is traced in the Galactic Center with a poloidal magnetic cylinder. MHD waves ejected from the nucleus are reflected and guided along the magnetic field, exhibiting vertically stretched fronts. The radio threads and non-thermal filaments are explained as due to tangential views of the waves driven by sporadic activity in Sgr A$^*$, or by multiple supernovae. In the latter case, the threads could be extremely deformed relics of old SNRs exploded in the nucleus.
