The dynamics of accretion discs around galactic and extragalactic black holes may be influenced by their magnetic field. In this paper we generalise the fully relativistic theory of stationary axisymmetric tori in Kerr metric of Abramowicz et al.(1978) by including strong toroidal magnetic field and construct analytic solutions for barotropic tori with constant angular momentum. This development is particularly important for the general relativistic computational magnetohydrodynamics that suffers from the lack of exact analytic solutions that are needed to test computer codes.

  1. Viscosity effects on the shadow of a non-rotating black hole

    gr-qc 2026-07 conditional novelty 5.0 of 10

    Shear viscosity and spacetime-curvature transport alter synthetic black hole shadow images of stationary magnetized tori at the few-μJy level.

  2. Neutrino spin oscillations near a black hole

    hep-ph 2025-02 conditional novelty 5.0 of 10

    Neutrinos scattered by a black hole's accretion disk undergo non-negligible spin flip from the toroidal magnetic field alone, contrary to earlier studies.

  3. Investigating the interplay of the braneworld gravity and the plasma environment on the black hole shadow

    gr-qc 2025-12 unverdicted novelty 4.0 of 10

    Negative tidal charge enlarges the shadow of rotating braneworld black holes while inhomogeneous plasma shrinks it and homogeneous plasma enlarges it; EHT data limits q to roughly -1.15 to 0.45 for M87* in the low-den...
