Timing and Spectral Analysis of the 2024 Outburst of 2S 1553542 with NuSTAR and NICER
Haifan Zhu, Wei Wang, Wen Yang +4
We report a timing and spectral study of the 2024 outburst of the Be/X-ray binary pulsar 2S~1553542 using \textit{NuSTAR} and \textit{NICER} observations. From the \textit{NuSTA…
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…
Millihertz quasi-periodic oscillations in accreting X-ray pulsars
Wen Yang, Wei Wang
Accreting neutron stars exhibit pulsed X-rays and complex temporal variability across multi-wavelengths and different timescales. This variability could be driven by various physic…
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…
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…
Studying the variations of the cyclotron line in Cen X-3 using Insight-HXMT
Qi Liu, Wei Wang, Wen Yang +2
We investigate the cyclotron resonant scattering features (CRSFs) of the accreting X-ray pulsar Cen X-3 and significantly detect the 29 keV cyclotron line features in the hard X-ra…
Evidence for a cyclotron absorption line and spectral transition in EXO 2030+375 during 2021 giant outburst
Wen Yang, Wei Wang, Prahlad R. Epili
Based on HXMT observations of EXO 2030+375 during its 2021 giant outburst, we report the analysis of pulse variations and the broadband X-ray spectrum, and find the presence of a p…
Periodicity of sub-pulses in a radio pulsar
Peng-Fu Tian, Ping Zhang, Wen Yang +2
Pulsars are known to manifest complex phenomena, such as nulling, sub-pulse drifting, and periodicity. Within the purview of this investigation, we have harnessed the wavelet analy…
