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…

On the detectability of gravitational waves emitted from head-on collisions of -boson stars
Mariana Lira, Laura O. Villegas, Javier M. Antelis +3
In this work, we investigate head-on collisions of -boson stars, potential candidates for dark matter compact objects. We begin with a review of the general properties and fe…

Full 3D nonlinear dynamics of charged and magnetized boson stars
VÃctor Jaramillo, DarÃo Núñez, Milton Ruiz +1
Gauged boson stars are exotic compact objects that can potentially mimic black holes or magnetized neutron stars in both their gravitational and electromagnetic signatures, offerin…
