Images of Braneworld black holes with radiatively inefficient accretion flows
Chengjia Chen, Yin Hao, Zelin Zhang +2
Horizon-scale imaging acts as a transformative tool for probing spacetime geometry, enabling stringent tests of gravitational theories in the strong-field regime. The Casadio-Fabbr…
Near-horizon polarized images of a rotating hairy Horndeski black hole
Chengjia Chen, Qiyuan Pan, Jiliang Jing
Recently, Hou \emph{et al.} [Astrophys. J. Lett. \textbf{988}, L51 (2025)] revealed that the Electric Vector Position Angle (EVPA) of polarization vectors in the near-horizon image…
Precessions of spherical orbits in the rotating Melvin black hole spacetime and its constraints from the jet of M87*
Chengjia Chen, Qiyuan Pan, Jiliang Jing
We investigate precessions of spherical orbits of timelike particles in the background of a rotating black hole immersed in the Melvin magnetic field, and probe effects of the magn…
Geometrically thick equilibrium tori around a Schwarzschild black hole in swirling universes
Chengjia Chen, Qiyuan Pan, Jiliang Jing
We study geometrically thick non-self gravitating equilibrium tori orbiting a Schwarzschild black hole immersed in swirling universes. This solution is axially symmetric and non-as…
Quasinormal modes of a scalar perturbation around a rotating BTZ-like black hole in Einstein-bumblebee gravity
Chengjia Chen, Qiyuan Pan, Jiliang Jing
We analytically study the quasinormal modes of a scalar perturbation around a rotating BTZ-like black hole in the Einstein-bumblebee gravity. We observe that the Lorentz symmetry b…
