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…
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…
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…
A White Dwarf Binary Candidate Discovered by LAMOST Using Dynamical Method
Haifan Zhu, Wei Wang, Xue Lib +2
We present the discovery of a binary system containing a white dwarf candidate using data from the LAMOST. Our analysis of the radial velocity data allowed us to determine an orbit…
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…
