论文摘要
最近发现了来自银河系SGR 1935+2154的毫秒无线电爆发,就磁铁与快速无线电爆发(FRB)之间的联系进行了激烈的讨论。尽管SGR 1935+2154的无线电爆发的某些特性与宇宙学的FRB并不相同,但有一些理论模型提出了磁铁和FRB之间的联系(请参阅Margalit等人的评论,2020年)。特别是,某些模型中包括磁星云的作用,因此,更详细地研究SGR 1935+2154的X射线环境是值得的。在这里,我们使用档案Chandra数据报告了SGR 1935+2154附近X射线瞬态功能的发现,并讨论其可能的起源。
The recent discovery of a millisecond radio burst from the Galactic magnetar SGR 1935+2154 has initiated an intense discussion about the connection between magnetars and fast radio bursts (FRBs). Although some properties of the radio burst from SGR 1935+2154 are not the same as cosmological FRBs, there are theoretical models which propose a connection between magnetars and FRBs (see review by Margalit et al. 2020). In particular, the role of a magnetar wind nebula is included in some models, and therefore it is worthwhile to investigate the X-ray environment of SGR 1935+2154 in more detail. Here, we report on the discovery of an X-ray transient feature near SGR 1935+2154 using archival Chandra data and discuss its possible origin.
