It is shown that the Kerr metric represents the nonlinear superposition of self-dual and anti-self-dual Taub-NUT instantons. This promotes the Newman-Janis algorithm to a rigorous derivation of the Kerr metric with a definite physical origin. In the same way, the Kerr-Newman and charged Kerr-Taub-NUT solutions are systems of Taub-NUT instantons and chiral dyons.

    gr-qc 2026-05 unverdicted novelty 5.0

    Kaluza-Klein boost on Kerr-Taub-NUT leaves horizon radius, entropy and temperature unchanged but enlarges the physical ergoregion volume and introduces a dyonic magnetic work term.

    gr-qc 2026-05 unverdicted novelty 5.0

    A Kaluza-Klein boost on Kerr-Taub-NUT enlarges the physical ergoregion volume without altering horizon radius, entropy, or temperature, while adding dyonic work terms to the first law.
