In this paper, we study the charged and uncharged BTZ counterpart of the Black-Bounce proposed by Simpson and Visser recently. For the uncharged case, we find that the temperature is not modified by the bounce parameter. We also find that the wormhole side of the solution must always be supported by exotic matter over the throat. For the charged case we find that the thermodynamics is changed and the bounce parameter controls a phase transition, affecting the sign of the heat capacity and therefore the stability of the system. For the uncharged case, we find that there are no stable orbits for both massive and massless incoming particles while stable orbits are present for the charged case and the bounce parameter affects the points of stability.

  1. A smooth BTZ black bounce with an extremal null throat

    gr-qc 2026-08 conditional novelty 6.0 of 10

    Inserting tanh((r-r_h)/delta) into the inverse radial BTZ metric produces a black bounce whose throat sits exactly at an extremal null horizon, with no Lorentzian-to-Riemannian signature change.

  2. On regular black string spacetimes in nonlinear electrodynamics

    gr-qc 2026-03 unverdicted novelty 6.0 of 10

    No regular purely electric black strings exist in NED recovering the Maxwell limit, but regular cylindrical Bardeen and Hayward analogues are constructed with finite curvature.

  3. Exact plane symmetric black bounce with a perfect-fluid exterior obeying a linear equation of state

    gr-qc 2025-06 conditional novelty 6.0 of 10

    A plane-symmetric perfect-fluid spacetime with a linear equation of state admits maximal extensions that are either a globally regular black bounce or a black hole with a spacelike singularity, depending on the interi...

  4. Spherically symmetric and static black bounces with multiple horizons, throats, and anti-throats in four dimensions

    gr-qc 2025-02 conditional novelty 5.0 of 10

    A new family of static, spherically symmetric black bounce spacetimes with multiple horizons, throats, and anti-throats is constructed and sourced by a partially phantom scalar field with nonlinear electrodynamics.

  5. Field Sources for Wormholes With Multiple Throats/Anti-throats

    gr-qc 2024-12 conditional novelty 4.0 of 10

    For a wormhole metric with multiple throats and anti-throats, the authors build explicit phantom-scalar-plus-nonlinear-electrodynamics sources and show the energy conditions can hold locally near the center.
