Electrically charged black holes with electroweak hair
Etevaldo dos Santos Costa Filho
We construct electrically charged black holes in Einstein's gravity coupled to the bosonic sector of the electroweak theory, focusing on static, spherically symmetric and asymptoti…
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…
Test-particle dynamics in a noncommutative deformation of Einstein-Rosen waves
Diego Henrique Carvalho dos Santos, José André Lourenço, Davi C. Rodrigues +1
We investigate phenomenological effects induced by a noncommutative deformation of Einstein--Rosen gravitational-waves within the framework of the Riemannian geometry of noncommuta…
Relativistic and Newtonian Proca Stars: A Tale of Two Limits
Alberto Diez-Tejedor, Carlos Herdeiro, Claudio Lazarte +4
We investigate a representative set of static solitonic solutions of the Einstein-Proca theory in the Newtonian regime, where the field frequency approaches the particle mass, $ω\t…
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)…
From rotating attractors to extremal black holes with axionic hair
Etevaldo dos Santos Costa Filho
We study extremal, rotating black holes in four-dimensional Einstein-Maxwell-axion (EMA) theory through a combined near-horizon and bulk analysis. At the level of the near-horizon…
