Two asymptotically flat spinning black holes balanced by their self-interacting, synchronised scalar hair
Chen Liang, Carlos Herdeiro, Eugen Radu
Asymptotically flat balanced configurations of two spinning black holes with synchronised scalar hair (2sBHs) are possible (arXiv:2305.15467). These are constructed within a genera…

Attractive and repulsive Yang-Mills--Higgs magnetic monopoles on
Francisco Navarro-Lérida, Eugen Radu, D. H. Tchrakian
An -gauged Higgs model on is proposed that, like the Abelian Higgs model on , features both attractive and repulsive phases, though unlike the l…

Multipolar Proca stars: electric, magnetic and hybrid solitons
Carlos Herdeiro, Eugen Radu, Etevaldo dos Santos Costa Filho +1
We construct new families of everywhere regular, asymptotically flat solitons in the Einstein--Proca model, obtained as self-gravitating continuations of flat-spacetime (singular)…
