Multirotating black holes with nonaligned angular momenta in 5D Kaluza-Klein theory

Year: 2026

Type: article

Abstract: We present an exact solution describing multirotating black holes in 4D Einstein-Maxwell-dilaton theory, which can be obtained from 5D Kaluza-Klein theory via dimensional reduction. The solution represents a multicentered configuration of rotating black holes carrying both electric and magnetic charges, with each black hole possessing a non-aligned angular momentum. This work generalizes our previous solution for black holes with aligned angular momenta to the more general case of nonaligned angular momenta. It includes, as special cases, the Majumdar-Papapetrou solution, the recent multicentered rotating black hole solutions of Teo and Wan, and our previous solution with unequal electric and magnetic charges. The resulting spacetimes are free of curvature singularities and closed timelike curves, both on and outside the horizons, provided that the magnitude of the spin angular momentum of each black hole remains below a certain upper bound. The absence of conical singularities has not been established for the general case with nonaligned angular momenta.
