Timing and Spectral Analysis of the 2024 Outburst of 2S 1553542 with NuSTAR and NICER
Haifan Zhu, Wei Wang, Wen Yang +4
The paper presents timing and spectral observations of the 2024 outburst of the Be/X‑ray binary pulsar 2S 1553‑542 using NuSTAR and NICER, measuring a 9.285 s pulse period, detecti…
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…
