In this paper we study the strong gravitational lensing scenario where the lens is a Reissner-Nordstrom black hole. We obtain the basic equations and show that, as in the case of Schwarzschild black hole, besides the primary and secondary images, two infinite sets of relativistic images are formed. We find analytical expressions for the positions and amplifications of the relativistic images. The formalism is applied to the case of a low-mass black hole placed at the galactic halo.

  1. Strong-deflection expansion of the deflection angle near a degenerate photon sphere

    gr-qc 2026-03 unverdicted novelty 7.0 of 10

    Derives a factorized leading term for the strong deflection angle near degenerate photon spheres using local expansion of the effective potential and Weyl tensor measures.

  2. Phase-plane formulation of weak gravitational deflection in static spherical spacetimes

    gr-qc 2026-08 accept novelty 6.0 of 10

    The Schwarzschild weak-deflection angle is derived to all orders from a phase-plane amplitude cubic, giving an explicit coefficient formula with convergence radius at the photon sphere.

  3. Strong field gravitational lensing of particles by a black-bounce-Schwarzschild black hole

    gr-qc 2026-02 accept novelty 5.0 of 10

    For a black-bounce-Schwarzschild black hole, the paper derives the strong-deflection lensing observables for massive particles and quantifies how they differ from photon lensing.

  4. 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.

  5. Gravitational Lensing by Black Holes in Einstein-nonlinear Electrodynamic Theories with Multiple Photon Spheres

    gr-qc 2025-07 conditional novelty 4.0 of 10

    In Einstein-nonlinear electrodynamic black holes, each effective potential peak that is taller than all peaks outside it yields a separate photon ring cluster in the lensed image, and triple-peak cases show three nest...
