We adopt general relativistic ray-tracing (GRRT) schemes to study images of Kerr-MOG black holes surrounded by geometrically thick magnetized equilibrium tori, which belong to steady-state solutions of thick accretion disks within the framework of general relativistic magnetohydrodynamics (GRMHD). The black hole possesses an extra dimensionless MOG parameter described its deviation from usual Kerr one. Our results show that the presence of the MOG parameter leads to smaller disks in size, but enhances the total flux density and peak brightness in their images. Combining with observation data of black hole M87* from the Event Horizon Telescope (EHT), we make a constraint on parameters of the Kerr-MOG black hole and find that the presence of the MOG parameter broadens the allowable range of black hole spin.

  1. Signatures of Lorentz violation in bright ring for Sgr A* images by radiation ineffective accretion flows

    astro-ph.HE 2026-08 conditional novelty 6.0 of 10

    For a rotating Lorentz-violating black hole, increasing the LV parameter shrinks and broadens Sgr A*'s image ring, and EHT data bound the parameter over a spin-dependent range.

  2. Critical Behavior of Photon Rings in Kerr-Bertotti-Robinson Spacetime

    gr-qc 2026-03 conditional novelty 6.0 of 10

    For a magnetized Kerr-Bertotti-Robinson black hole, the photon-ring parameters gamma, delta, and tau all decrease compared with the unmagnetized Kerr case, weakening the self-similar stacking of higher-order images.

  3. Optical Images of the Braneworld Black Hole Surrounded by an Optically Thin Accretion Disk

    astro-ph.HE 2026-07 conditional novelty 5.0 of 10

    A rotating braneworld black hole with tidal charge casts an asymmetric, spin- and q-dependent shadow; with the adopted disk emissivity, its 86 GHz image is brighter than its 230 GHz image.
