Ground calibration and network of the first CATCH pathfinder
Yiming Huang, Jingyu Xiao, Lian Tao +53
The Chasing All Transients Constellation Hunters (CATCH) space mission is focused on exploring the dynamic universe via X-ray follow-up observations of various transients. The firs…
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…
A timing view of the additional high-energy spectral component discovered in the black hole candidate Swift J1727.8-1613
Zi-Xu Yang, Liang Zhang, Shuang-Nan Zhang +15
We present an energy-dependent analysis for the type-C quasi-periodic oscillations (QPOs) observed in the black hole X-ray binary Swift J1727.8-1613 using Insight-HXMT observations…
Polarization Perspectives on Hercules X-1: Further Constraining the Geometry
Qingchang Zhao, Hancheng Li, Lian Tao +24
We conduct a comprehensive analysis of the accreting X-ray pulsar, Hercules X-1, utilizing data from IXPE and NuSTAR. IXPE performed five observations of Her X-1, consisting of thr…
Insights from the Gaussian Processes Method for the FRB-associated X-ray Burst of SGR 1935+2154
Ruijing Tang, Dahai Yan, Haiyun Zhang +7
Gaussian processes method is employed to analyze the light curves of bursts detected by Insight-HXMT, NICER, and GECAM from SGR 1935+2154 between 2020 to 2022. It is found that a s…
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…
Timing analysis of the newly discovered black hole candidate Swift J1727.8-1613 with Insight-HXMT
Wei Yu, Qing-Cui Bu, Shuang-Nan Zhang +9
We present the results obtained from an X-ray timing study of the new black hole candidate (BHC) Swift J1727.8-1613. The work is based on Hard X-ray Modulation Telescope (Insight-H…
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…
Simulation Studies for the First Pathfinder of the CATCH Space Mission
Yiming Huang, Juan Zhang, Lian Tao +42
The Chasing All Transients Constellation Hunters (CATCH) space mission is an intelligent constellation consisting of 126 micro-satellites in three types (A, B, and C), designed for…
Studies on the soft intermediate state X-ray flare of MAXI J1535-571 during its 2017 outburst
Ruican Ma, Lian Tao, Mariano Méndez +15
We analyzed an observation with the Nuclear Spectroscopic Telescope Array of the black-hole X-ray binary MAXI J1535-571 in the soft intermediate state, in which we detected a 2.5-k…
