Abstract: We review some literature about gravitational collapse and discuss how some scenarios can lead to the formation of naked singularities. References: gr-qc/0312123, gr-qc/0308012, gr-qc/0109051, gr-qc/9804075.
Abstract: The knowledge of the Universe is essentially based on the theory of general relativity (GR). If from one hand, solar system data is in excellent agreement to the theory, available cosmological evidence on the other, is consistent with GR provided one assumes the existence of dark energy and dark matter.
Abstract: I briefly present the baselines of Quantum Field Theory in Curved Spacetimes (QFTCS), which investigates the consequences of defining a quantum field theory for the matter and its interactions in a curved spacetime background described by General Relativity. Although being na effective theory, QFTCS allows the prediction of quantum gravity effects, like thermal eva
Abstract: One of the most interesting and current phenomenological extensions of General Relativity is the so-called f(R) class of theories; a natural generalization of this includes an explicit non-minimal coupling between matter and curvature.
Abstract: In this talk I will discuss the coupling of massive scalar fields to matter in orbit around rotating black holes. It is generally expected that orbiting bodies will lose energy in gravitational waves, slowly inspiralling into the black hole.
Abstract: We discuss a new theory of gravity, recently proposed by Banados and Ferreira. This theory is inspired by an original proposal by Eddington and it is equivalent to General Relativity in vacuum. However, it dramatically differs from Eistein's gravity inside matter.
Abstract: In this talk we discuss several aspects of black holes with electric charge within General Relativity. We first consider the historical context and different applications of non-linear electrodynamics in the physics of black holes and Cosmology.
Abstract: In this talk I will discuss ongoing work on using head on gravitational shock wave collisions in higher dimensional spacetimes to estimate the gravitational radiation emitted in transplanckian collisions.
