We compute the shadows of colliding black holes using the Kastor-Traschen cosmological multiblack hole solution that is an exact solution describing the collision of maximally charged black holes with a positive cosmological constant. We find that in addition to the shadow of each black hole, an eyebrowlike structure appears as the black holes come close to each other. These features can be used as probes to find the multiblack hole system at the final stage of its merger process.

  1. Spinning generalizations of Majumdar-Papapetrou multi-black hole spacetimes: light rings, lensing and shadows

    gr-qc 2025-02 conditional novelty 6.0 of 10

    For the Teo-Wan two-black-hole spacetime, light rings merge and annihilate in pairs, giving total counts of 4, 6, or 8, and the shadows mimic double-Kerr.
