Impact of electric charges on chaos in magnetized spacetimes
Daqi Yang, Wenfang Liu, Xin Wu
We consider the motion of test particles around a black hole immersed into a strong external magnetic field modifying the spacetime structure. When the particl…

Parameter constraints from shadows of Kerr-Newman-dS black holes with cloud strings and quintessence
Wen-Fu Cao, Wen-Fang Liu, Xin Wu
The motion of photons around the Kerr-Newman-dS black hole surrounded by quintessence and a cloud of strings is investigated. The existence of the Carter constant leads to that of…

Study of chaos in rotating galaxies using extended force-gradient symplectic methods
Li-Na Zhang, Wen-Fang Liu, Xin Wu
We take into account the dynamics of three types of models of rotating galaxies in polar coordinates in a rotating frame. Due to non-axisymmetric potential perturbations, the angul…
