非热射电丝(NTFs)于40多年前首次在20厘米波长处被发现,是银心最神秘的结构之一,至今仍缺乏清晰的解释。这些引人注目的窄特征追踪着强磁场,常与银道面形成鲜明对比。近期发现了令人惊讶的关联:一些非热射电丝与呈现Fe He-α发射的X射线丝对齐。本文呈现了一项正在进行的合作多波段研究的初步结果,旨在理解这些丝的起源,重点测试这些关联的磁重联场景,并为我们银河系中心极端条件下的高能过程和磁现象提供新的见解。
英文摘要
Nonthermal radio filaments (NTFs), first discovered at 20-centimeter wavelength more than four decades ago, are among the most enigmatic structures at the Galactic Center. They still defy a clear explanation. These striking narrow features trace intense magnetic fields and often stand in bold contrast to the Galactic plane. Recent discoveries have revealed surprising associations: some NTFs align well with X-ray threads that seem to exhibit Fe He-$α$ emission. Here, I present preliminary results from an ongoing, collaborative, multi-wavelength study aimed at understanding the origins of these filaments, focusing on testing the magnetic reconnection scenario of these associations and shedding new light on the high-energy processes and magnetic phenomena operating under extreme conditions at the heart of our Galaxy.
