Statistical properties of type-II bursts in Rapid Burster observed with Insight-HXMT
Shi-peng Wang, Long Ji
We report the detection of type-II X-ray bursts in a neutron star low mass X-ray binary MXB 1730-335 (also known as Rapid Burster) observed with Insight- HXMT satellite. We found s…
Detection of disk-jet co-precession in a tidal disruption event
Yanan Wang, Zikun Lin, Linhui Wu +46
Theories and simulations predict that intense spacetime curvature near black holes bends the trajectories of light and matter, driving disk and jet precession under relativistic to…
IGR J17091-3624: Newly Formed Periodic Dips and Multiwavelength Activity During the 2025 Outburst
Zikun Lin, Yanan Wang, Shuyuan Wei +15
The black hole low-mass X-ray binary (LMXB) candidate IGR J17091-3624 experienced a hard-state-only outburst in 2025. In this paper, we show that IXPE detected a series of intermit…
Highly Polarized Intrinsic Emission and its Orthogonal Counterpart in Vela X-1
WanYun Wu, Fei Xie, Long Ji +2
Vela X-1 is one of the most archetypal wind-fed X-ray pulsars (XRPs), and the emergence of its orthogonal polarization states reveals distinctive polarimetric properties. Using dat…
Revealing an Oscillating and Contracting Compact Corona near the Event Horizon of the Supermassive Black Hole in 1ES 1927+654
Qing-Cang Shui, Shu Zhang, Shuang-Nan Zhang +7
Dynamic processes in the accretion flow near black holes produce X-ray flux variability, sometimes quasi-periodic. Determining its physical origin is key to mapping accretion geome…
Orbital phase shifts of Type-I outbursts in EXO 2030+375
Run-Ting Huang, Long Ji, Jing-Zhi Yan
EXO 2030+375 is a peculiar high-mass X-ray binary that has been exhibiting Type-I outburst activities consistently over the past decades. The phases of outburst peaks are generally…
