It is shown that the 4D Einstein-Klein-Gordon equations with a phantom scalar field (a scalar field with a negative sign in front of the kinetic energy term of its Lagrange density) has non-singular, spherically symmetry solutions. These solutions have a combination of features found in other spherically symmetric gravity plus field solutions. A stability analysis on these solutions indicates they are unstable.

  1. Shadow of the Scalar Hairy Black Hole with Inverted Higgs Potential

    gr-qc 2025-01 unverdicted novelty 4.0 of 10

    Hairy black hole shadows and disks grow with horizon scalar value but can mimic Schwarzschild by adjusting horizon radius, with the potential parameter Lambda constrained by supermassive black hole observations.

    gr-qc 2024-11 reject novelty 3.0 of 10

    The paper constructs phantom-scalar wormhole metrics and reverse-engineers a symmetry-breaking potential, but the solution does not satisfy the stated field equations for generic parameters and the photon-sphere radiu...

    gr-qc 2012-02 unverdicted novelty 2.0 of 10

    Boson stars are particle-like solutions in general relativity that model dark matter, black hole mimickers, and binary systems.
