A Phase-resolved View of "Heartbeat"-like variability in IGR J17091-3624 During the 2022 Outburst
Qing-Cang Shui, Shu Zhang, Jing-Qiang Peng +9
IGR J17091-3624, in addition to GRS 1915+105, is the only black hole X-ray binary that displays ``heartbeat"-like variability characterized by structured flares with high amplitude…
Phase-resolved Spectroscopy of Low-frequency Quasi-periodic Oscillations from the Newly Discovered Black Hole X-ray Binary Swift J1727.8-1613
Qing-Cang Shui, Shu Zhang, Jiang-Qiang Peng +14
Low-frequency quasi-periodic oscillations (LFQPOs) are commonly observed in X-ray light curves of black hole X-ray binaries (BHXRBs); however, their origin remains a topic of debat…
Recovery of High-energy Low-frequency Quasi-periodic Oscillations from Black Hole X-ray Binary MAXI J1535-571 with a Hilbert-Huang Transform Method
Qingcang Shui, Shu Zhang, Shuangnan Zhang +15
We propose a method based on the Hilbert-Huang transform (HHT) to recover the high-energy waveform of low-frequency quasi-periodic oscillations (LFQPOs). Based on the method, we su…
Cyclotron line evolution revealed with pulse-to-pulse analysis in the 2020 outburst of 1A 0535+262
Qingcang Shui, Shu Zhang, Pengju Wang +17
We present a detailed analysis of the X-ray luminosity (Lx) dependence of the cyclotron absorption line energy (Ecyc) for the X-ray binary pulsar 1A 0535+262 during its 2020 giant…
Likely detection of magnetic field related LFQPO in the soft X-ray re-brightening of GRS~1915+105
Ling-Da Kong, Long Ji, Andrea Santangelo +3
Utilizing NICER observations, we present an analysis of the soft X-ray re-brightening event of GRS 1915+105 observed in 2021. During this event, we observed the emergence of a stab…
Broadband noise and quasi-periodic oscillation characteristics of the X-ray pulsar RX J0440.9+4431
P. P. Li, L. Tao, R. C. Ma +15
We present a comprehensive timing analysis on the Be/X-ray binary pulsar RX J0440.9+4431 using observations from \textit{NICER} and \textit{Insight}-HXMT during the 2022--2023 outb…
The First Polarimetric View on Quasi-Periodic Oscillations in a Black Hole X-ray Binary
Qingchang Zhao, Lian Tao, Hancheng Li +19
We present the first polarimetric analysis of Quasi-Periodic Oscillations (QPO) in a black hole binary utilizing \textit{IXPE} data. Our study focuses on Swift J1727.8--1613, which…
