In this paper, we use the strong field limit approach to investigate the gravitational lensing properties of braneworld black holes. Applying this method to the supermassive black hole at the centre of our galaxy, the lensing observables for some candidate braneworld black hole metrics are compared with those for the standard Schwarzschild case. It is found that braneworld black holes could have significantly different observational signatures to the Schwarzschild black hole.

  1. Probing Lorentz Symmetry Violation through Lensing Observables of Rotating Black Holes

    gr-qc 2025-08 reject novelty 5.0 of 10

    A rotating Bumblebee black hole is shown to produce strong-lensing observables that deviate from Kerr, with EHT shadow data and an Einstein ring observation used to constrain the Lorentz-violating parameter ell.

  2. Strong gravitational lensing by black hole in F(R) Euler Heisenberg Gravity's Rainbow

    astro-ph.GA 2025-07 conditional novelty 4.0 of 10

    Applying the strong deflection limit to the F(R)-Euler-Heisenberg-Rainbow black hole gives lensing observables that increase with the Euler-Heisenberg parameter and decrease with charge.

  3. Strong gravitational lensing effects around rotating regular black holes

    gr-qc 2024-12 conditional novelty 4.0 of 10

    Strong lensing by rotating regular black holes shifts lensing coefficients, image positions, magnifications, and time delays relative to Kerr, with M87* time delays differing by up to tens of hours while image positio...
