In this work, we calculate the deflection angle of light in a spacetime that interpolates between regular black holes and traversable wormholes, depending on the free parameter of the metric. Afterwards, this angular deflection is substituted into the lens equations which allows to obtain physically measurable results, such as the position of the relativistic images and the magnifications.

    gr-qc 2026-06 unverdicted novelty 5.0

    Gravitational tension screening, acting as an analogue of Schwinger corrections, generates regular black bounce spacetimes for spherical, planar, and hyperbolic sections without ad hoc cores.

  3. Three dimensional black bounces in $f(R)$ gravity

    gr-qc 2026-01 conditional novelty 5.0

    Black bounce geometries exist in 2+1D f(R) gravity with scalar-nonlinear electrodynamics matter, including vanishing scalar curvature solutions whose viability is checked via scalaron mass and energy conditions.

  4. Roche limit and stellar disruption in the Simpson--Visser spacetime

    gr-qc 2026-01 unverdicted novelty 5.0

    Tidal forces in the Simpson-Visser spacetime produce Roche radii for stars that depend on observer type and regularization, with some disruptions occurring outside the event horizon for supermassive black holes.

  5. On relativistic observables in black bounce spacetimes

    gr-qc 2026-07 conditional novelty 4.0

    Black bounce spacetimes with larger throat parameter α produce enhanced periastron precession, light deflection, and a larger critical impact parameter in the wormhole regime, offering potential observational signatures.
