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.

Dynamical formation of hairy rotating black holes
In a recent remarkable work just published in Physical Review Letters as an Editor's suggestion, William East and Frans Pretorius (E&P) studied the non-linear growth of the superradiant instability. And the endpoint matches hairy black holes discovered by the Gr@v team. Read here a viewpoint article by Sam Dolan.
Carolina Benone's PhD exam
Carolina Benone successfully defended her PhD thesis "Scalar fields in black hole spacetimes and analogues". The exam took place in U. Federal do Pará, in Belém, Brazil, on July 14th 2017. The thesis was supervised by Luis Crispino (UFPa) and Gr@v member C. Herdeiro. Congratulations Carolina!
Strong Gravity Universe in Azores
Group members P. Cunha and C. Herdeiro were two of the participants in the "Strong Gravity Universe" workshop, in S. Miguel island, Azores. This meeting was co-sponsored by the GWVerse COST action and StronGrHEP RISE network.
Gr@v research in "90 segundos de Ciência"
"90 seconds of Ciencia" is a daily programme of the National Public Radio, Antena 1. Hear in this link the contribution of Gr@v researchers to this excellent show that makes accessible to a larger audience the research made in Portugal, across all fields of knowledge.
