Gr@v member Valério Ribeiro was part of an international team of researchers studying thermonuclear eruptions in the Andromeda galaxy. The team published, in Nature magazine, the discovery of a super-nova remnant which is bigger than most supernova remnants. They found that the super-nova remnant was the consequence of yearly repeated eruptions over millions of years. Few of these systems are known in the galaxy due to the fact that we suffer from dust obscuration.
Gr@v member João Rosa was one of the recipients of the 2018 Alberto prize, awarded by the Portuguese Society of Relativity and Gravitation (SPRG). The prize was given for his work on the phenomenon of superradiance and its physical and astrophysical implications. The prize was shared by Richard Brito, a researcher of the Max Planck Institute for Gravitational Physics, in Berlin, Germany. The prize was delivered at the General Assembly of the SPRG, on 19th December 2018, during the XI Black Holes Workshop.
Gr@v member Pedro Cunha was one of the invited lecturers of the V Amazonia Workshop on Black Holes and Analogue Models of Gravity, that took place at the Federal University of Pará, in Belém, Brazil, from December 3rd to 7th, 2018. Cunha gave five lectures on "Geodesics and Shadows of Kerr black holes".
The Brazilian Funding Agency, CAPES, presented Carolina Benone's PhD Thesis with an Honorable Mention. This award results from a Brazilian national contest for the PhD theses defended in 2017. Carolina's thesis was supervised by Professor Luis Carlos Crispino from Universidade Federal do Pará (UFPA), Brazil, and includes research performed with Gr@v members, as a result of two long term visits of Carolina's to Gr@v during her PhD. Hearty congratulations Carolina!
From October 2018 onwards, Carlos Herdeiro, one of Gr@v's founding members, became an Associate Professor at the Physics Department of IST-Lisbon.

Abstract: In this talk, we present whether the new ekpyrotic scenario
can be embedded into ten-dimensional supergravity. We use that the
scalar potential obtained from flux compactifications of type II
supergravity with sources has a universal scaling with respect to the
The XI Black Holes Workshop will take place at IST-Lisbon on 17-18 December 2018. The Black Holes Workshops gather researchers working on physical and mathematical problems of black holes, both in its classical and quantum aspects, as well as their connections to general relativity and gravitation, string theory, cosmology, and astrophysics, and stimulate the interaction between all these issues.
