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…
Particle Acceleration in Cassiopeia A Revealed by Broadband High-Energy Spectrum
Bo-Tao Li, Wei Wang, Zhuo Li
Recently, the GeV--sub-PeV spectrum of supernova remnant (SNR) Cassiopeia A (Cas A), one of the youngest and most well-studied SNRs in our Galaxy, has been updated by observations…
Different polarized components of the quasar 3C 286 revealed by FAST
Pengfu Tian, Xiao Chen, Wen Yang +1
3C 286, a well-known radio calibrator, exhibits the stability in both of total flux density (FD) and polarization parameters. However, its stable and luminous interstellar radio si…
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…
Insight-HXMT Spectral and Timing Studies of a Giant Outburst in RX J0440.9+4431
Prahlad R. Epili, Wei Wang
The Be/X-ray binary pulsar RX J0440.9+4431 underwent a giant outburst in late 2022 and lasted three months. The Insight-HXMT has observed this source at several instances of the en…
Timing and spectral variability in 2S 1417-624 observed with Insight-HXMT
Qi Liu, Lingda Kong, Can Güngör +5
We present the results of the spectral and timing analyses of the accreting X-ray pulsar, 2S 1417-624, during the 2018 and 2021 outbursts with Insight-HXMT. We find that the pulse…
