论文摘要
新发现的银河黑洞候选人（BHC）Maxi〜J1348-630在发现之后，2019年显示了2019年的两次主要爆发。在这里，我们使用来自多个卫星的档案数据（即Swift，Maxi，Nicer，Nostar和Astrosat）提供了较少研究的第二次爆发的详细光谱和时间分析。爆发持续了大约两个半月。与此消息来源的第一次爆发不同，第二次爆发是“失败”。源未转变为软光谱状态或中间光谱状态。在整个爆发期间，源处于硬状态，非热光子的优势很高。使用TCAF模型从光谱拟合中推断出强电击的存在。在Nustar光谱中，通过光谱拟合观察到弱反射。在Astrosat数据中还检测到低频准周期振荡。
The newly discovered galactic black hole candidate (BHC) MAXI~J1348-630 showed two major outbursts in 2019, just after its discovery. Here, we provide a detailed spectral and temporal analysis of the less-studied second outburst using archive data from multiple satellites, namely Swift, MAXI, NICER, NuSTAR and AstroSat. The outburst continued for around two and a half months. Unlike the first outburst from this source, this second outburst was a `failed' one. The source did not transition to soft or intermediate spectral states. During the entire outburst, the source was in the hard state with high dominance of non-thermal photons. The presence of strong shocks are inferred from spectral fitting using a TCAF model. In NuSTAR spectra, weak reflection is observed from spectral fitting. Low-frequency quasi-periodic oscillations are also detected in AstroSat data.
