-Boson stars in anti-de Sitter spacetime
Miguel Megevand
In previous work, we introduced the -boson stars, a generalization of standard boson stars, which are parameterized by an angular momentum number , while still preservi…
Noble gravitational atoms: Self-gravitating black hole scalar wigs with angular momentum number
Miguel Alcubierre, Juan Barranco, Argelia Bernal +5
We present new spherically symmetric solutions of the Einstein-Klein-Gordon equations in a quasi-stationary approximation that describe self-gravitating scalar field configurations…
Gravitational atoms beyond the test field limit: The case of Sgr A* and ultralight dark matter
Miguel Alcubierre, Juan Barranco, Argelia Bernal +5
We construct gravitational atoms including self-gravity, obtaining solutions of the Einstein-Klein-Gordon equations for a scalar field surrounding a non-rotating black hole in a qu…
Boson stars and their relatives in semiclassical gravity
Miguel Alcubierre, Juan Barranco, Argelia Bernal +5
We construct boson star configurations in quantum field theory using the semiclassical gravity approximation. Restricting our attention to the static case, we show that the semicla…
Head-on collisions of -boson stars
Víctor Jaramillo, Nicolas Sanchis-Gual, Juan Barranco +5
Fully non-linear numerical evolutions of the Einstein-(multi)--Klein-Gordon equations are performed to study head-on collisions of -boson stars. Despite being spherically sym…
Extreme -boson stars
Miguel Alcubierre, Juan Barranco, Argelia Bernal +6
A new class of complex scalar field objects, which generalize the well known boson stars, was recently found as solutions to the Einstein-Klein-Gordon system. The generalization co…
