High energy physics involves the study of the fundamental building blocks of nature at the shortest distances. These are the fundamental particles that are described by quantum fields such as the Higgs field found at CERN's Large Hadron Collider (LHC). Our group studies theories beyond the Standard Model of particle physics both from theoretical and phenomenological perspectives.

"The extreme gravity of astrophysical compact objects", a workshop integrated in the NewFunFiCO network took place in Frankfurt in June 2026. A great atmosphere, a variety of interesting science and lively discussions made a great event. The photo was taken in the rooftop of the venue, the historical building where the Stern-Gerlach experiment was conducted in 1922.
In April 2026 we received the visits of Maryem Jemri (Rabat) and Justin Feng (Prague). Thank you for your seminars and the great scientific interactions!
I will discuss the first 3D-general relativistic magnetohydrodynamic (GRMHD) simulation of sustained accretion onto a horizonless singularity in which matter falls onto the central object rather than being accumulated outside of it or expelled in outflows.
Gr@v is hosting the visits of Yasha Shnir, long time group collaborator, under an FCT mobility grant, and Mario Luciano Navarro, Ph.D. student from Valencia in the spring 2026. In the photo Yasha and Mario enjoy a bit of sunshine after the weekly group lunch.
Our group is co-organizing the X Amazonian Workshop on Gravity and Analogue Models from 29 June to 3 July in Belém, Brazil. More info here.
