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.

Dyson, just before the first detection of Gravitational Waves (GWs) by LIGO, raised the question of whether the detection of a single graviton can be achieved with GW strain detectors. If this is possible, then it would be a direct evidence for the quantization of the gravitational field.

group meeting

25-11-25 was a wonderful day of celebration of past achievements, present efforts, and future horizons. It was a real joy to see so many colleagues, collaborators, and friends, that are part of the history, present and future of Gr@v, either online or onsite. Thank you to all that have contributed to the first fifteen years of Gr@v, in this amazing epoch to work on strong gravity; we look forward to the next fifteen years!

Celebrating Strong Gravity - 25 - 11 - 25

Workshops

On November 25, 1915, Einstein presented the field equations of General Relativity to the Prussian Academy of Sciences. A hundred and ten years later, we celebrate the remarkable progress of the field of strong gravity — its many achievements, the 15th anniversary of the Aveiro Gr@v group (est. 2010), and a decade since the first detection of gravitational waves.
