Visits Maryem Jemri and Justin Feng
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!
High Energy Physics
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.
For our latest developments/activities in this area, please see the listing below.

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.
Visits Yasha Shnir and Mario Navarro
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.
