Blázquez Salcedo, José Luis ; González Romero, Luis Manuel ; Kunz, Jutta ; Mojica, Sindy ; Navarro Lérida, Francisco | Amer Physical Soc | 2016-01-28We investigate axial quasinormal modes of realistic neutron stars in Einstein-Gauss-Bonnet-dilaton gravity. We consider eight realistic equations of state containing nuclear, hyperonic, and hybrid matter. We focus on the fundamental curvature mo[...]texto impreso
Blázquez Salcedo, José Luis ; Kunz, Jutta ; Navarro Lérida, Francisco ; Radu, Eugen | Amer Physical Soc | 2017-03-13We consider rotating black hole solutions in five-dimensional Einstein-Maxwell-Chern-Simons theory with a negative cosmological constant and a generic value of the Chern-Simons coupling constant.. Using both analytical and numerical techniques, [...]texto impreso

We study the effect of a Chern-Simons term on the electrically charged and spinning solitons of several U(1) gauged models in 2 + 1 dimensions. These are vortices of complex scalar field theories, both with and without symmetry breaking dynamics[...]texto impreso
We study spherically symmetric finite energy solutions of two Higgs-Chern-Simons-Yang-Mills-Higgs (HCS-YMH) models in 3 + 1 dimensions, one with gauge group SO(5) and the other with SU(3). The Chern-Simons (CS) densities are defined in terms of [...]texto impreso
Blázquez-Salcedo, José Luis ; Kunz, Jutta ; Navarro Lérida, Francisco ; Radu, Eugen | Amer Physical Soc | 2018-04-16A new class of black hole solutions of the five-dimensional minimal gauged supergravity is presented. They are characterized by the mass, the electric charge, two equal magnitude angular momenta and the magnitude of the magnetic potential at inf[...]texto impreso
Blázquez Salcedo, José Luis ; González Romero, Luis Manuel ; Navarro Lérida, Francisco ; Tchrakian, D. H. | Amer Physical Soc | 2013-07-16We 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 improved numerical codes and found some unexpected features we did [...]texto impreso
The question of the dependence of the topological charge q of a gauged Skyrmion, on the gauge field, is studied quantitatively. Two examples, both gauged with SO (2) are studied and contrasted: i) The O (3) model in 2 + 1 dimensions, and ii) The[...]texto impreso
Blázquez Salcedo, José Luis ; González Romero, Luis Manuel ; Navarro Lérida, Francisco | Amer Physical Soc | 2013-05-31Here we investigate the axial w quasinormal modes of neutron stars for 18 realistic equations of state, most of them satisfying the 2M condition. In particular, we study the influence of the presence of hyperons and quarks in the core of the ne[...]texto impreso
Blázquez Salcedo, José Luis ; Kunz, Jutta ; Navarro Lérida, Francisco ; Radu, Eugen | Amer Physical Soc | 2015-08-17Rotating black holes in Einstein-Maxwell-Chern-Simons theory possess remarkable features when the Chern-Simons coupling constant reaches a critical value. Representing single asymptotically flat black holes with horizons of spherical topology, t[...]texto impreso
Blázquez Salcedo, José Luis ; Kunz, Jutta ; Navarro Lérida, Francisco ; Radu, Eugen | Elsevier Science BV | 2017-08-10We construct a generalization of the AdS charged rotating black holes with two equal magnitude angular momenta in five-dimensional minimal gauged supergravity. In addition to the mass, electric charge and angular momentum, the new solutions poss[...]texto impreso
We study the simplest SO(2) gauged O(5) Skyrme model in 4 + 1 (flat) dimensions. In the gauge decoupled limit, the model supports topologically stable solitons (Skyrmions) and after gauging, the static energy of the solutions is bounded from bel[...]texto impreso
Blázquez Salcedo, José Luis ; Kunz, Jutta ; Navarro Lérida, Francisco ; Radu, Eugen | Springer | 2018-02-09We construct a new class of black hole solutions in five-dimensional Einstein-Maxwell-Chern-Simons theory with a negative cosmological constant. These configurations are cohomogeneity-1, with two equal-magnitude angular momenta. In the generic c[...]texto impreso
Blázquez Salcedo, José Luis ; Kunz, Jutta ; Navarro Lérida, Francisco ; Radu, Eugen | Multidisciplinary Digital Publishing Institute | 2016-12We construct a new class of Einstein-Maxwell static solutions with a magnetic field in D-dimensions (with D > = 5 an odd number), approaching at infinity a globally Anti-de Sitter (AdS) spacetime. In addition to the mass, the new solutions posse[...]texto impreso
In this paper we prove that in a stationary axisymmetric SU(2) Einstein-Yang-Mills theory the most reasonable circularity conditions that can be considered for the Yang-Mills fields imply in fact that the field is of embedded Abelian type, or el[...]
