Signature of iron line profile from a Kerr-like wormhole
Cheng Liu, Hoongwah Siew, Hong-Xuan Jiang +2
Broad, skewed iron K emission lines in the X-ray spectra of accreting black holes encode key information about the spacetime geometry of the innermost disk. While the Kerr metri…
Radiative Cooling Effects on Plasmoid Formation in Black Hole Accretion Flows with Multiple Magnetic Loops
Jing-Ze Xia, Hong-Xuan Jiang, Yosuke Mizuno +2
We investigate the influence of radiative cooling on plasmoid formation in black hole accretion flows using 2D and 3D two-temperature GRMHD simulations with multi-loop magnetic fie…
Quasi-Periodic Polarized Emissions from Kink Structure in Magnetized Relativistic Jets
Xu-Fan Hu, Hong-Xuan Jiang, Yosuke Mizuno +2
Recent polarimetric observations of blazars indicate the development of current-driven (CD) kink instability after passing the recollimation shocks in the relativistic jets and ass…
The Physical Origin and Time Lag of Multi-Frequency Flares from SgrA*
Hong-Xuan Jiang, Yosuke Mizuno, Indu K. Dihingia +5
Sagittarius~A, the supermassive black hole at the center of our galaxy, exhibits flares across various wavelengths, yet their origins remain elusive. We performed 3D two-temper…
Magnetically Driven Retrograde Precession in Misaligned Black Hole Accretion Flows
Hong-Xuan Jiang, Yosuke Mizuno, Dong Lai +2
Observations of accreting black hole (BH) systems, such as microquasars and supermassive black holes, often reveal a precessing jet with changing directions, indicating a misaligne…
