The hard and quiescent states of black hole X-ray binaries and most supermassive black holes in the nearby universe are powered by hot accretion flows. In this talk, I will review wind and jet launched from this type of accretion flow, including both their theoretical studies and observaitonal evidences. For winds, we will introduce their launching mechanism and main properties such as mass...

伽马射线射线双星是X射线双星的一个特殊子类,它们在各个波段都有很强的辐射,适合多波段观测研究。 LS I +61 303是伽马射线双星中最为特殊的一个源,受到国内外众多学者的关注、研究,是国内多个(不同波段)望远镜的重要观测对象。最近,我们利用FAST在LS I +61 303方向首次探测到脉冲信号,说明系统中很可能存在一个年轻的强磁场中子星。在此基础上,我们利用FAST和慧眼卫星对其进行长期监测,希望进一步深入了解该系统。

It has been well known for a long time that a black hole X-ray binary stays in the hard state when the luminosity is low (below around one percent of LEdd). The X-ray spectrum is dominated by the inverse Compton emission from a hot corona, which is very different from the thermal dominated spectrum from Shakura-Sunyaev disk at higher luminosity. In recent years, however, some observational...

The main methods applied to study X-ray binaries are timing and spectral analysis. Compared to other instruments, Insight-HXMT covers a broad energy band from 1 to 250 keV with a high time resolution and a moderate spectral resolution. Moreover, Insight-HXMT does not suffer from strong pileup effects and instrumental dead time. We have taken these advantages of Insight-HXMT to study two black...
