X-Ray Views of Galactic Accreting Pulsars in High-Mass X-Ray Binaries
Shan-Shan Weng, Long Ji
Accreting X-ray pulsars, located in X-ray binaries, are neutron stars with magnetic fields as strong as G. This review offers a concise overview of the ac…
Einstein Probe discovery of EP J005245.1-722843: a rare BeWD binary in the Small Magellanic Cloud?
A. Marino, H. Yang, F. Coti Zelati +32
On May 27 2024, the Wide-field X-ray Telescope onboard the Einstein Probe (EP) mission detected enhanced X-ray emission from a new transient source in the Small Magellanic Cloud (S…
A comprehensive comparison of spin-up and spin-down episodes of 4U 1538-522 observed with NuSTAR
Y. F. Hu, L. Ji, C. Yu
4U 1538-522 is a persistent high mass X-ray binary which exhibits secular spin evolution. In 2019, it underwent a torque reversal from spinning up to spinning down. We performed an…
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…
A Transition Discovered in the Subcritical Regime of 1A 0535+262
Hua Xiao, Long Ji
We present NICER observations of accreting X-ray pulsar 1A 0535+262 during its faint state ( erg/s) observed in several type I and II outbursts. We discove…
