Strong Gravity

The group's research on strong gravity involves finding analytical and numerical solutions of Einstein's theory of general relativity, and many of its extensions, either in vacuum or coupled to various types of matter. For our latest developments/activities in this area, please see the listing at the end of this article.

The prime examples of (relativistic) strong gravitational systems are Black Holes. They are truly unifying objects of all physics. The understanding of their formation and dynamics requires the laws of all four fundamental forces, and their physics is relevant not only for astrophysics and cosmology but for a variety of topics within high energy physics.

See here a movie made by the COST action `Black holes in a violent universe', in which our group participates, for a visual overview of different types of black holes.

CAPES Honorable Mention for Carolina Benone's Thesis

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!

Carlos Herdeiro becomes Associate Professor at IST-Lisbon

From October 2018 onwards, Carlos Herdeiro, one of Gr@v's founding members, became an Associate Professor at the Physics Department of IST-Lisbon. The photo shows group members and Yves Brihaye, visiting from Mons University, enjoying a wonderful "parrilhada de peixe", by the seaside, a few kilometers from the Aveiro Campus, on September 28th 2018.

Visit of Kunihito Uzawa

Professor Kunihito Uzawa from Kwansei Gakuin University, Japan, visited Gr@v in the last week of September 2018 and gave a seminar on "No-Go theorems for ekpyrosis from ten-dimensional supergravity". (In the photo with Eugen Radu.)

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
