Abstract: In general relativity a single massive real scalar field can form long living stable oscillating localized configurations, which are generally called oscillatons. These objects are quite similar to the well known boson stars.
The paper "Shadows of Kerr black holes with scalar hair" by P. Cunha, C. Herdeiro, E. Radu and H. Rúnarsson has been accepted in Physical Review Letters. This work shows Kerr black holes with scalar hair can exhibit new types of shadows in black hole physics. Observing black hole shadows is the primary target of the Event Horizon Telescope.
Gr@v is a partner of the recently approved "Strong Gravity and High Energy Physics" Marie Curie RISE (Research and Innovation Staff Exchange) action, within the Horizon 2020 European framework. This network has a lifetime of 4 years, starting in Jan 2016 and connects 8 nodes in 7 countries, being coordinated by Prof. Ulrich Sperhake and Cambridge University.
Abstract: I will present a detailed study of the Entanglement Entropy for the confining Klebanov-Strassler background coupled to a large number of dynamical flavors.
The V global meeting of the Numerical Relativity and High Energy Physics Marie Curie IRSES action, took place in Universidade Federal do Pará, Belém, Brazil, from 28 September -2 October 2015.
Thank you Luis Carlos Crispino for the stimulating meeting in the beautiful Amazonia.
Living Reviews in Relativity has been one of the most prestigous journals in the field of Gravitation. After interrupting its activity in September 2014, it was recently acquired by Springer and has now resumed publication with the new review articles: "Exploring New Physics Frontiers Through Numerical Relativity" co-authored by our group.

Pedro Cunha presented his M.Sc thesis on September 21st 2015, on the topic of "Black Hole Shadows". A student at the University of Coimbra, Pedro chose to do his M.Sc. thesis within Gr@v. His impressive work led him to be awarded a 20 (out of 20) for his thesis, the first ever in the Master programme he attended, and to write an original paper on "Shadows of Kerr black holes with scalar hair".
To celebrate the centenial of General Relativity and simulataneously celebrate five years of the Gravitation Group at the University of Aveiro (Gr@v), established in the Fall 2010, Gr@v will organize a two days event, on 25-26 November 2015. This event will also mark the closing of the "Numerical Relativity and High Energy Physics" Marie Curie IRSES action, an international partnership which was coordinated by our group that ran over the period 2012-2015. Finally, the event will also be integrated in the IDPASC doctoral programme.
