-modes of neutron stars in a massless scalar-tensor theory
Jose Luis Blázquez-Salcedo, Luis Manuel González-Romero, Fech Scen Khoo +2
Scalar-tensor theories allow for a rich spectrum of quasinormal modes of neutron stars. The presence of the scalar field allows for polar monopole and dipole radiation, as well as…
Non-Abelian Chern-Simons-Higgs vortices with a quartic potential
J. L. Blazquez-Salcedo, L. M. Gonzalez-Romero, F. Navarro-Lerida +1
We have constructed numerically non-Abelian vortices in an SU(2) Chern-Simons-Higgs theory with a quartic Higgs potential. We have analyzed these solutions in detail by means of im…
Non-singular G2 stiff fluid cosmologies
L. Fernandez-Jambrina, L. M. Gonzalez-Romero
In this paper we analyse Abelian diagonal orthogonally transitive spacetimes with spacelike orbits for which the matter content is a stiff perfect fluid. The Einstein equations are…
Non-singular radiation cosmological models
L. Fernandez-Jambrina, L. M. Gonzalez-Romero
In this paper we analyse the possibility of constructing singularity-free inhomogeneous cosmological models with a pure radiation field as matter content. It is shown that the cond…
A wide family of singularity-free cosmological models
L. Fernandez-Jambrina, L. M. Gonzalez-Romero
In this paper a family of non-singular cylindrical perfect fluid cosmologies is derived. The equation of state corresponds to a stiff fluid. The family depends on two independent f…
Exterior Differential System for Cosmological G2 Perfect Fluids and Geodesic Completeness
L. Fernandez-Jambrina, L. M. Gonzalez-Romero
In this paper a new formalism based on exterior differential systems is derived for perfect-fluid spacetimes endowed with an abelian orthogonally transitive G2 group of motions act…
