Polarized quasi-periodic oscillations reveal kink instability in magnetized jets of black holes

Jiashi Chen, Pengfu Tian, Wei Wang

The dynamics and instability of the magnetized jets connected to jet acceleration are complicated and are not yet well understood. Quasi-periodic oscillations (QPOs) as special tim…

Quasi-periodic oscillations and reflection feature evolution in 4U 1630-47 observed with Insight-HXMT

Jiashi Chen, Wei Wang

The Galactic black hole (BH) X-ray binary 4U 1630-47 went into a new outburst in 2021 after 600 days from its 2020 outburst. We perform a detailed analysis of quasi-periodic…

The spin measurement of the black hole SLX 1746-331 using Insight-HXMT observations

Jiashi Chen, Wei Wang

We present an X-ray spectral analysis of a black hole X-ray binary SLX 1746-331 during the 2023 outburst using five \textit{Insight}-HXMT observations. We jointly use the reflectio…

Quasi-periodic oscillations of GHz-band polarization in a black hole

Wei Wang, Jiashi Chen, Pengfu Tian +10

Relativistic jets from accreting black holes (BHs) radiate non-thermal emission which is highly variable in different time scales. Magnetic fields anchored to a rotating BH or accr…

The spin of a stellar black hole 4U 1543-47 determined by Insight-HXMT

Jiashi Chen, Wei Wang

We present a spectral analysis of \textit{Insight}-HXMT observations of the low-mass X-ray binary 4U 1543-47 which locates in our Milky Way galaxy during the 2021 outburst. We focu…

Sub-second periodic radio oscillations in a microquasar

Pengfu Tian, Ping Zhang, Wei Wang +18

Powerful relativistic jets are one of the ubiquitous features of accreting black holes in all scales. GRS 1915+105 is a well-known fast-spinning black-hole X-ray binary with a rela…

A moderate spin for the black hole in X-ray binary MAXI J1348-630 revealed by Insight-HXMT

Hanji Wu, Wei Wang, Na Sai +2

MAXI J1348-630 is a low-mass X-ray black hole binary located in the Galaxy and undergone the X-ray outburst in 2019. We analyzed the observation data in very soft state during the…

X-ray from Outflow-Cloud Interaction and Its Application in Tidal Disruption Events

Jiashi Chen, Wei Wang

Tidal disruption events (TDEs) may occur in supermassive black holes (SMBHs) surrounded by clouds. TDEs can generate ultrafast and large opening-angle outflow with a velocity of $\…
