Relativistic Thermal Emission from Accretion Disks in Kerr-MOG Spacetimes
Cheng Liu, Xu-fan Hu, Yosuke Mizuno +1
In Scalar-Tensor-Vector Gravity (STVG, also known as MOG), a massive vector field generates a repulsive fifth force that endows rotating black holes with a gravitational ch…

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…

Numerical Investigation of Instabilities in Over-pressured Magnetized Relativistic Jets
Xu-Fan Hu, Yosuke Mizuno, Christian M. Fromm
Context. Relativistic jets from Active Galactic Nuclei are observed to be collimated on the parsec scale. When the pressure between the jet and the ambient medium is mismatched, re…
