Black holes: accretion processes in X-ray binaries
Qingcui Bu, Shuangnan Zhang
Accretion onto black holes is one of the most efficient energy source in the Universe. Black hole accretion powers some of the most luminous objects in the universe, including quas…
The mHz quasi-regular modulations of 4U 1630--47 during its 1998 outburst
Qingchang Zhao, Hongxing Yin, Lian Tao +19
We present the results of a detailed timing and spectral analysis of the quasi-regular modulation (QRM) phenomenon in the black hole X-ray binary 4U 1630--47 during its 1998 outbur…
Hilbert-Huang Transform analysis of quasi-periodic oscillations in MAXI J1820+070
Wei Yu, Qing-Cui Bu, Zi-Xu Yang +14
We present time-frequency analysis, based on the Hilbert-Huang transform (HHT), of the evolution on the low-frequency quasi-periodic oscillations (LFQPOs) observed in the black hol…
A spectral-timing study of the inner flow geometry in MAXI J1535--571 with -HXMT and NICER
Wei Yu, Qing-Cui Bu, He-Xin Liu +48
We have performed a spectral-timing analysis on the black hole X-ray binary MAXI J1535--571 during its 2017 outburst, with the aim of exploring the evolution of the inner accretion…
In-orbit background simulation of a type-B CATCH satellite
Jingyu Xiao, Liqiang Qi, Shuang-Nan Zhang +23
The Chasing All Transients Constellation Hunters (CATCH) space mission plans to launch three types of micro-satellites (A, B, and C). The type-B CATCH satellites are dedicated to l…
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…
