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…
Self-interacting scalar field distributions around Schwarzschild black holes
Alejandro Aguilar-Nieto, Víctor Jaramillo, Juan Barranco +3
Long-lived configurations of massive scalar fields around black holes may form if the coupling between the mass of the scalar field and the mass of the black hole is very small. In…
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…
Preliminary Study on Dark Matter-Dominated Systems: Further Analysis for galactic dark matter halos with Pressure
Andrés Aceña, Juan Barranco, Argelia Bernal +2
Low surface brightness galaxies are an excellent laboratory where stars and baryonic matter act as tracers of the gravitational potential of the dark matter halo. If dark matter is…
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…
Scalar field dark matter with two components: combined approach from particle physics and cosmology
Eréndira Gutiérrez-Luna, Belen Carvente, Víctor Jaramillo +5
In this work we explore the possibility of incorporating particle physics motivated scalar fields to the dark matter cosmological model. In this landscape, we consider the classica…
