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…
Spinning extremal dyonic black holes in Einstein-Maxwell-dilaton theory
Jose Luis Blázquez-Salcedo, Carlos Herdeiro, Eugen Radu +2
We propose a general framework for the study of asymptotically flat spinning dyonic {\it extremal} black holes (eBHs) in Einstein-Maxwell-dilaton theory. Restricting to the s…
Charged, rotating black holes in Einstein-Maxwell-dilaton theory
Carlos Herdeiro, Eugen Radu, Etevaldo dos Santos Costa Filho
The asymptotically flat, electrically charged, rotating black holes (BHs) in Einstein-Maxwell-dilaton (EMd) theory are known in closed form for \textit{only} two particular values…
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)…
Stability and collisions of excited spherical boson stars: glimpses of chains and rings
Marco Brito, Carlos Herdeiro, Eugen Radu +2
Scalar, spherically symmetric, radially excited boson stars were previously shown to be stabilized, against spherical dynamics, by sufficiently strong self-interactions. Here, we f…
