A Revised Spin of the Black Hole in GRS 1716-249 with a New Distance
S. J. Zhao, L. Tao, Q. Q. Yin +12
GRS 1716-249 is a stellar-mass black hole in a low-mass X-ray binary that underwent a gaint outburst in 2016/17. In this paper we use simultaneous observations of Insight-HXMT and…

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…

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…
