Boson Star Factory: Past, Present, and Future
Romain Gervalle, Jorge Filipe Mónico Delgado, Etevaldo dos Santos Costa Filho +4
Boson stars are self-gravitating solitons of the Einstein-Klein-Gordon equations for a massive complex scalar field, and arguably the simplest horizonless compact objects arising i…
Bosonic stars with dark electroweak fields
Etevaldo dos Santos Costa Filho, Romain Gervalle
We construct bosonic stars in the Einstein-Weinberg-Salam theory, namely the bosonic sector of the electroweak Standard Model minimally coupled to Einstein's theory of gravity. The…
Black holes with electroweak hair -- the detailed derivation
Romain Gervalle, Mikhail S. Volkov
We present a very detailed derivation of solutions describing hairy black holes within the gravity-coupled Weinberg-Salam theory, which were previously reported in \href{https://do…
Hairy black holes and other compact objects in theories of gravity
Romain Gervalle
In the realm of spacetimes governed by Einstein's general relativity and containing only Maxwell's electromagnetic field, stationary black holes are fully characterized by their ma…
Black holes with electroweak hair
Romain Gervalle, Mikhail S. Volkov
We construct static and axially symmetric magnetically charged hairy black holes in the gravity-coupled Weinberg-Salam theory. Large black holes merge with the Reissner-Nordström (…
Electroweak multi-monopoles
Romain Gervalle, Mikhail S. Volkov
We construct the multi-charge generalizations for the electroweak magnetic monopole solution of Cho and Maison within a wide range of values of the magnetic charge. We use the same…
Chains of rotating boson stars
Romain Gervalle
Boson Stars are stationary, axially symmetric solutions of a complex scalar field theory coupled to gravity. Recently, multi-solitonic configurations interpreted as static chains o…
Electroweak monopoles and their stability
Romain Gervalle, Mikhail S. Volkov
We apply a generalized field ansatz to describe the spherically symmetric sector of classical solutions of the electroweak theory. This sector contains Abelian magnetic monopoles l…
Asymptotically flat hairy black holes in massive bigravity
Romain Gervalle, Mikhail S. Volkov
We study asymptotically flat black holes with massive graviton hair within the ghost-free bigravity theory. There have been contradictory statements in the literature about their e…
