论文摘要
在银河系中心，快速模式磁磁动力学（MHD）压缩波的传播。由活性银河核（SGR A）产生的MHD波关注分子云（例如中央分子区域的SGR B），这将触发恒星形成或可能是Starburst。 MHD波被Starburst向后传播，并专注于核（SGR A），其中内爆的波会压缩核气，以促进核加油并可能触发核活性。通过最小的能量需求，以高效率触发了SGR A（活跃的银河核：AGN）和SGR B（Starburst）之间MHD波的聚焦。它还解决了AGN加油的角动量问题，因为聚焦波不需要全球气体流动。
Propagation of fast-mode magneto-hydrodynamic (MHD) compression waves is traced in the Galactic Centre. MHD waves produced by the active Galactic nucleus (Sgr A) focus on the molecular clouds such as Sgr B in the central molecular zone, which will trigger star formation, or possibly starburst. MHD waves newly excited by the starburst propagate backward, and focus on the nucleus (Sgr A), where implosive waves compress the nuclear gas to promote fueling the nucleus and may trigger nucleus activity. Echoing focusing of MHD waves between Sgr A (active galactic nucleus: AGN) and Sgr B (starburst) trigger each other at high efficiency by minimal energy requirement. It also solves the problem of angular momentum for AGN fueling, as the focusing waves do not require global gas flow.
