A comprehensive study of time delay between optical/near-infrared and X-ray emissions in black hole X-ray binaries
Dizhan Du, Bei You, Zhen Yan +3
We conducted a comprehensive study of daily delays using multi-wavelength data from a sample of well-studied black hole X-ray binaries, specifically focusing on the sources GX 339-…
Exploring variation of double-peak broad-line profile in strongly variable AGNs
Jiancheng Wu, Qingwen Wu, Kaixing Lu +4
The geometry and kinematics of the broad-line region (BLR) in AGNs are still unclear, which is crucial for studying the physics and evolution of supermassive black holes (SMBHs) an…
Magnetic Flux Transport in Advection Dominated Accretion Flow Towards the Formation of Magnetically Arrested Disk
Jia-Wen Li, Xinwu Cao
The magnetically arrested disks (MADs) have attracted much attention in recent years. The formation of MADs are usually attributed to the accumulation of a sufficient amount of dyn…
A physical model for radio and X-ray correlation in black hole X-ray binaries
Yiheng Jiang, Shanshan Li, Xinwu Cao +3
A tight correlation between the radio and X-ray emission in the hard state of black hole X-ray binaries (BHXRBs) indicates an intrinsic disc-jet connection in stellar black hole ac…
Do all the quasars and high-excitation radio galaxies (HERGs) in the 3CRR catalog contain a magnetically arrested disk (MAD)?
Shuang-Liang Li, Wenwen Zuo, Xinwu Cao
Based on the magnetization, an accretion disk with large-scale magnetic field can be separated into either standard and normal evolution (SANE) or magnetically arrested disk (MAD),…
The delayed radio emission in the black hole X-ray binary MAXI J1348630
Bei You, Shuai-kang Yang, Zhen Yan +2
We explore the coupling between the accretion flow and the jet in black hole X-ray binary (BHXRB) MAXI J1348-630 by analyzing the X-ray and radio observations during its 2019 outbu…
Instability of Circumnuclear Gas Supply as An Origin of "Changing-look" Phenomenon of Supermassive Blackholes
J. Wang, D. W. Xu, Xinwu Cao +3
The origin of the "Changing-look" (CL) phenomenon in supermassive black holes (SMBHs) remains an open issue. This study aims to shed light on this phenomenon by focusing on a sampl…
Exploring the properties of photosphere and emission lines for tidal disruption events based on the global solution of slim disk and winds
Yuehua Zhang, Qingwen Wu, Jiancheng Wu +2
The theoretical debris supply rate from a tidal disruption of stars can exceed about one hundred times of the Eddington accretion rate for a supermassive black…
Magnetically arrested disks in FR I radio galaxies
Han He, Bei You, Ning Jiang +5
A sample of 17 FR I radio galaxies constructed from the 3CR catalog, which is characterized by edge-darkened radio structures, is studied. The optical core luminosities derived fro…
