Juan Carlos Degollado Daza, who has been a post-doctoral research at Gr@v since 2012, working on numerical relativity, has accepted a permanent professor position at the University of Guadalajara, Mexico. Congratulations Juan Carlos, well done!
Abstract: (2+1)-dimensional gravity allows us to study aspects of classical and quantum gravity in a simpler technical setting which retains much of the conceptual complexity of the standard (3+1)-dimensional gravity. However, pure Einstein gravity lacks propagating degrees of freedom in 2+1 dimensions.
Abstract: Teleparallel gravity is an alternative theory of gravitation. It is entirely equivalent to General Relativity in what concerns dynamical evolution. The main advantage of such a theory is that in its realm it is possible to define an expression for the gravitational energy.
Abstract: The talk will focus on two problems: Black holes formation by particle collisions in quantum physics.The approach which will be presented is based on constructing a horizon wave-function which yields the probability of finding a black hole horizon of a certain radius centered around the source.
The III Amazonian workshop on black holes and analogue models of gravity will take place in UFP, Belém do Pará, Brazil, from 4-7 August 2014. This is a satellite workshop of the IRSES Marie Curie action on "Numerical Relativity and High Energy Physics", of which the U. Aveiro and UFP are both partners.

Abstract: In general relativity, masslessness of gravitons can be traced to symmetry under diffeomorphisms. However, another elegant possibility exists: masslessness can instead arise from spontaneous violation of local Lorentz invariance. We construct the corresponding theory of gravity.
