Gr@v and MAP-PDMA Ph.D. student João Oliveira was awareded an "Outstanding Presentation Award - Gold Prize" for his scientific presentation at the 29th workshop on General Relativity and Gravitation, in Japan, at the University of Kobe.
More than 200 researchers participated in this conference, of which 66 were selected to deliver oral presentations. Of these, 56 were nominated for the outstanding presentation award, but only 4 were awarded this distinction, including João Oliveira.
The V Amazonian Symposium on Physics was held in Belém, Brazil, from 18-22 November 2019. This meeting was co-sponsored by the Marie Curie RISE FunFiCO network and co-organised by Gr@v members. The invited speakers included Bill Unruh, Bob Wald, John Friedman, Jorge Zanelli and Mirjam Cvetic, amongst others.
Gra@v members C. Herdeiro and E. Radu, together with Nuno Santos from IST-Lisbon, visited Universidade Federal do Pará (UFPa), Brazil, in Amazonia, during November 2019, within the Marie Curie RISE FunFiCO partnership. In the photon in the river Guamá, with Carolina Benone, a former UFPa/Aveiro PhD student, now staff at UFPa.
Gr@v members C. Herdeiro and E. Radu, were two of the speakers of the Mini-workshop on "Black holes and symmetries" at the Instituto de Física, Pontifica Universidad Católica Valparaíso, Chile. The workshop was organised by Olivera Moskovic and Dumitru Astefanesei. The other speaker was Marc Henneaux from the Université Libre de Bruxelles, Belgium.
Gr@v Ph.D. students Alexandre Pombo, João Oliveira and Jorge Delgado visited Kindai University, Japan as members of the StronGrHEP Marie Curie RISE project. Their host is Professor Akihiro Ishibashi.
In this work, we study cosmological and astrophysical applications of the recently proposed generalized hybrid metric-Palatini gravity theory, which combines features of both the metric and th
In this talk we will discuss the quasinormal modes of neutron stars in modified theories of gravity, in particular, in R^2 gravity. In this model, in addition to the space-time and fluid degrees of freedom that are present in General Relativity, we naturally find a (massive) scalar field.
Spontaneous scalarization is an interesting phenomenon that black holes with a sufficiently large mass or charge spontaneously transit to a solution with
The existence of light, fundamental bosonic fields is an attractive possibility that can be tested via black hole observations.
We study the effect of a tidal field -- caused by a companion star or black hole -- on the evolution of superradiant scalar-field states around spinning black holes.
Our group coordinated the "Numerical Relativity and High Energy Physics" IRSES network (2012-2015). Here is a list of the global network meetings organized:
