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…
Determination of the angular momentum of the Kerr black hole from equatorial geodesic motion
Laura O. Villegas, Eduardo Ramirez-Codiz, Víctor Jaramillo +4
We present a method to determine the angular momentum of a black hole, based on observations of the trajectories of the bodies in the Kerr space-time. We use the Hamilton equations…
Magnetostatic boson stars
Víctor Jaramillo, Darío Núñez
We solve the Einstein-Maxwell-Klein-Gordon system of equations and derive a compact, static axially symmetric magnetized object which is electrically neutral and made of two comple…
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…
