Fast transitions of X-ray variability in the black hole transient GX 339--4: comparison with MAXI J1820+070 and MAXI J1348-630
Zi-Xu Yang, Liang Zhang, S. N. Zhang +30
Fast transitions between different types of power density spectra (PDS) happening over timescales of several tens of seconds are rare phenomena in black hole X-ray binaries. In thi…
Investigation of the emission radii of kHz QPOs for the accreting millisecond X-Ray pulsars, Atoll and Z sources
D. H. Wang, L. Chen, C. M. Zhang +3
We infer the emission positions of twin kilohertz quasi-periodic oscillations (kHz QPOs) in neutron star low mass X-ray binaries (NS-LMXBs) based on the Alfven wave oscillation mod…
The rms-flux relations in different branches in Cyg X-2
Z. B. Li, L. M. Song, J. L. Qu +3
In this paper, the rms-flux (root mean square-flux) relation along the Z-track of the bright Z-Source Cyg X-2 is analyzed using the observational data of Rossi X-ray Timing Explore…
Morphological analysis on the coherence of kHz QPOs
J. Wang, H. K. Chang, C. M. Zhang +4
We take the recently published data of twin kHz quasi-period oscillations (QPOs) in neutron star (NS) lowmass X-ray binaries (LMXBs) as the samples, and investigate the morphology…
The energy dependence of the centroid frequency and phase lag of the QPOs in GRS 1915+105
J. L. Qu, F. J. Lu, Y. Lu +3
We present a study of the centroid frequencies and phase lags of the quasi-periodic oscillations (QPOs) as functions of photon energy for GRS 1915+105. It is found that the centroi…
Evolution of cross-correlation and time lag of Cyg X-2 along the branches
Y. J. Lei, J. L. Qu, L. M. Song +6
We report the detections of the anti-correlated soft and hard X-rays, and the time lags of hecto-second from the neutron star low-mass X-ray binary Cyg X-2, a well-known Z-t…
