Traversable wormholes with double layer thin shells in quadratic gravity
Joao Luís Rosa, Rui André, José P. S. Lemos
In quadratic gravity, the junction conditions are six and permit the appearance of double layer thin shells. Double layers arise typically in theories with dipoles, i.e., two oppos…

Observational properties of relativistic fluid spheres with thin accretion disks
João Luís Rosa
In this work we analyze the observational properties of incompressible relativistic fluid spheres with and without thin-shells, when surrounded by thin accretion disks. We consider…

Multi-kink braneworld configurations in the scalar-tensor representation of gravity
D. Bazeia, A. S. Lobão, João Luís Rosa
In this work we investigate the brane in the scalar-tensor representation, where the solutions of the equations of motions for the source field engender topological defect…
