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.

New CIDMA scientific coordinator
Carlos Herdeiro, Gr@v member and founder, took office on 1 October as the new Scientific Coordinator of CIDMA, beginning a four-year term. The new coordination team also includes Natália da Costa Martins, Maria Elisa Carrancho Fernandes, and Nelson Filipe Loureiro Vieira. UA News coverage here. We wish the team every success in this new chapter.
Schwarzschild black holes as low-pass filters of fuzzy dark matter granularity
Gr@v work covered in Science Alert
A recently published paper by Gr@v (J. Ferreira et al. [PRD 114 (2026) 064005]) was covered by Science Alert. Read the news piece here.
Ernst-like Formalism and Exact Solutions in Einstein–Maxwell/ModMax–Scalar Gravity
We present an Ernst-like formalism for stationary and axisymmetric Einstein–Maxwell/ModMax gravity coupled to a scalar field. The Maxwell sector is recovered as a particular limit of the ModMax theory, allowing both theories to be studied within the same framework.
