Static black hole solutions with a self interacting conformally coupled scalar field
Gustavo Dotti, Reinaldo J. Gleiser, Cristian Martinez
We study static, spherically symmetric black hole solutions of the Einstein equations with a positive cosmological constant and a conformally coupled self interacting scalar field.…

Gravitational instability of static spherically symmetric Einstein-Gauss-Bonnet black holes in five and six dimensions
Martin Beroiz, Gustavo Dotti, Reinaldo J. Gleiser
Five and six dimensional static, spherically symmetric, asymptotically Euclidean black holes, are unstable under gravitational perturbations if their mass is lower than a critical…

Soliton propagation on a gravitational plane-wave collision spacetime
Gabriel B. Nagy, Reinaldo J. Gleiser, Andres D. Dagotto
We present a new family of exact solutions of the Einstein equations, constructed through the Khan-Penrose procedure, that may be interpreted as representing the propagation of a p…
