Measurement of the Orbital Parameters, Spin and Spectral Evolution During the Main High State of Her X-1 with Insight-HXMT

Wen Yang, Wei Wang, Qianhan Zhou

Based on Insight-HXMT observations, we present a detailed timing analysis and spectral evolution of a complete Main High state for Her X-1 in February 2020. We determine an accurat…

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…
