Instability of wormholes supported by a ghost scalar field. I. Linear stability analysis
J. A. Gonzalez, F. S. Guzman, O. Sarbach
We examine the linear stability of static, spherically symmetric wormhole solutions of Einstein's field equations coupled to a massless ghost scalar field. These solutions are para…

Constraining a bulk viscous matter-dominated cosmological model using SNe Ia, CMB and LSS
Arturo Avelino, U. Nucamendi, F. S. Guzmán
We present and constrain a cosmological model which component is a pressureless fluid with bulk viscosity as an explanation for the present accelerated expansion of the universe. W…

Scalar Field Dark Matter: head-on interaction between two structures
Argelia Bernal, F. Siddhartha Guzman
In this manuscript we track the evolution of a system consisting of two self-gravitating virialized objects made of a scalar field in the newtonian limit. The Schrödinger-Poisson s…
