Bumpy horizons from non-linear sigma models
Fabrizio Canfora, Nicolás Grandi, Carla Henr\'ıquez-Báez +1
We show that black hole horizons with non-constant curvature can be constructed in any even dimension, when the source of the Einstein equations is given by the stress-energy tenso…
A smooth road to bumpy horizons: shaping black holes with non-linear sigma models, from supergravity to higher dimensions
Fabrizio Canfora, Nicolás Grandi, Carla Henríquez-Báez +1
We construct new families of solutions for General Relativity coupled to a general class of non-linear sigma models, some of which can be embedded in supergravity. The solutions in…
Self-gravitating baryonic tubes supported by - and -mesons and its flat limit
Gonzalo Barriga, Carla Henríquez-Baez, Leonardo Sanhueza +1
In this paper, we construct self-gravitating topological solitons in the Einstein non-linear sigma model coupled to -vector mesons in four space-time dimensions. These s…
corrections to the black string instability and the boosted black string
Carla Henríquez-Báez, Julio Oliva, Marcelo Oyarzo +1
We consider a perturbative Gauss-Bonnet term supplementing the Einstein-Hilbert action, and evaluate its effect on the spectrum of the scalar mode that triggers the Gregory-Laflamm…
Black holes and black strings in the Einstein -non-linear sigma model
Carla Henríquez-Báez, Marcela Lagos, Aldo Vera
We construct analytical solutions describing black holes and black strings in the Einstein -non-linear sigma model in dimensions. This construction is carried out us…
On the stability of homogeneous black strings in AdS
Carla Henríquez-Báez
In this paper we extend the analysis of the stability of an homogeneous black string in the presence of a negative cosmological constant with minimally coupled scalar fields. We re…
