Detection of multiple X-ray quasi-periodic oscillations in IGR J19294+1816 with Insight-HXMT
Wen Yang, Wei Wang
We report the timing results with Insight-HXMT observations of X-ray binary IGR J19294+1816 during its 2019 Type I outburst at the decline phase shortly following its peak. We anal…

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…

Observations of the X-ray Millihertz Quasiperiodic Oscillations in Hercules X-1
Wen Yang, Wei Wang
With a systematic timing investigation of the persistent X-ray binary pulsar Her X-1 based on a large number of Insight-HXMT observations between 2017 to 2019, we confirm the prese…
