The effect of Chern-Simons dynamics on the energy of electrically charged and spinning vortices
Francisco Navarro-Lerida, Eugen Radu, D. H. Tchrakian
We study the effect of a Chern-Simons term on the electrically charged and spinning solitons of several gauged models in dimensions. These are vortices of complex scal…
Constraining Black Holes with Light Boson Hair and Boson Stars using Epicyclic Frequencies and QPOs
Nicola Franchini, Paolo Pani, Andrea Maselli +4
Light bosonic fields are ubiquitous in extensions of the Standard Model. Even when minimally coupled to gravity, these fields might evade the assumptions of the black-hole no-hair…
Astrophysical imaging of Kerr black holes with scalar hair
F. H. Vincent, E. Gourgoulhon, C. Herdeiro +1
We address the astrophysical imaging of a family of deformed Kerr black holes (BHs). These are stationary, asymptotically flat black hole (BH) spacetimes, that are solutions of Gen…
Inside black holes with synchronized hair
Yves Brihaye, Carlos Herdeiro, Eugen Radu
Recently, various examples of asymptotically flat, rotating black holes (BHs) with synchronized hair have been explicitly constructed, including Kerr BHs with scalar or Proca hair,…
Shadows of Kerr black holes with and without scalar hair
Pedro V. P. Cunha, Carlos A. R. Herdeiro, Eugen Radu +1
For an observer, the Black Hole (BH) shadow is the BH's apparent image in the sky due to the gravitational lensing of nearby radiation, emitted by an external source. A recent clas…
Kerr black holes with Proca hair
Carlos Herdeiro, Eugen Radu, Helgi Runarsson
Bekenstein proved that in Einstein's gravity minimally coupled to one (or many) real, Abelian, Proca field, stationary black holes (BHs) cannot have Proca hair. Dropping Bekenstein…
Scalar field dark matter and the Higgs field
Orfeu Bertolami, Catarina Cosme, João G. Rosa
We discuss the possibility that dark matter corresponds to an oscillating scalar field coupled to the Higgs boson. We argue that the initial field amplitude should generically be o…
Einstein-Maxwell-Anti-de-Sitter spinning solitons
Carlos Herdeiro, Eugen Radu
Electrostatics on global Anti-de-Sitter (AdS) spacetime is sharply different from that on global Minkowski spacetime. It admits a multipolar expansion with everywhere regular, fini…
