Black holes in Licán Ray, Chile
C. Herdeiro is one of the lecturers in the Licán Ray meeting, Chile, on Black Hole Physics, at the end of January 2026.
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.

Visit of Zakaria Belkhadria
Gr@v had the pleasure to host Zakaria Belkhadria (Université de Genève/Università degli Studi di Cagliari) who gave the group seminar on Dec 12th 2025.
New Aspects of spontaneous scalarization of black holes beyond General relativity
Speaker

Hybrid: Sala 11.2.21 and Teams
Event type
Spontaneous scalarization is a mechanism that allows black holes to develop a non-trivial profile of a scalar field “scalar hair” because of tachyonic instabilities, enabling tests of gravity beyond General Relativity.
FCT funded 3-years research fellowships at Gr@v
Gr@v is welcoming expressions of interest for the 8th edition of the CEEC competition. This call will fund three-year postdoctoral research contracts, offered at two levels depending on the applicant’s experience. Interested researchers are invited to contact the group coordinator. Application deadline: 29 January 2026.
Visits of Panagiotis Dorlis and Hendrik Mannenga
In the first week of December 2025 we had the pleasure of hosting Panagiotis Dorlis and Hendrik Mannenga, visiting from Athens and Oldenburg. Panagiotis gave an intersting seminar on How much gravitons can be squeezed. Many thanks for your visits!
