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.

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.

Seminars in Prague

The Gr@v coordinator, C. Herdeiro, visited Prague to deliver two seminars, at CEICO and Charles University. The visit provided a great opportunity to reconnect with friends and colleagues in a city rich in scientific and cultural heritage - home to figures such as Kepler, Tycho Brahe, Einstein, Doppler, Mach, Bolzano, and Kafka. Many thanks to both groups for their kind hospitality and for making this visit possible.
