A Phase-resolved View of the Low-frequency Quasiperiodic Oscillations from the Black Hole Binary MAXI J1820+070
Qing C. Shui, S. Zhang, Shuang N. Zhang +21
Although low-frequency quasiperiodic oscillations (LFQPOs) are commonly detected in the X-ray light curves of accreting black hole X-ray binaries, their origin still remains elusiv…
Type-A quasi-periodic oscillation in the black hole transient MAXI J1348-630
Liang Zhang, Mariano Méndez, Federico García +12
We present a detailed analysis of the spectral and timing characteristics of a 7-Hz type-A quasi-periodic oscillation (QPO) detected in NICER observations of the black hole X-ray b…
Detection of a strong ~2.5 Hz modulation in the Newly Discovered Millisecond Pulsar MAXI J1816-195
P. P. Li, L. Tao, L. Zhang +16
MAXI J181-195 is a newly discovered accreting millisecond X-ray pulsar that went outburst in June 2022. Through timing analysis with NICER and NuSTAR observations, we find a transi…
Spin measurement of 4U 1543-47 with Insight-HXMT and NICER from its 2021 outburst: A test of accretion disk models at high luminosities
E. S. Yorgancioglu, Q. C. Bu, A. Santangelo +7
4U 1543--47 is one of a handful of known black hole candidates located in the Milky Way Galaxy, and has undergone a very bright outburst in 2021, reaching a total of 9 Crab,…
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…
X-ray Polarimetry of the accreting pulsar 1A~0535+262 in the supercritical state with PolarLight
Xiangyun Long, Hua Feng, Hong Li +25
The X-ray pulsar 1A 0535+262 exhibited a giant outburst in 2020, offering us a unique opportunity for X-ray polarimetry of an accreting pulsar in the supercritical state. Measureme…
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…
Insight-HXMT and GECAM-C observations of the brightest-of-all-time GRB 221009A
