High Energy Physics


High Energy Physics (HEP) performs exciting, cutting-edge theoretical and experimental research in Quantum Fields, Particles and Gravity. The scientific aim of the department is to understand the ultimate building blocks of matter, space, and time and the fundamental laws governing their interaction at extremely high energies and short distances, beyond currently established theories. 

The High Energy Physics department is part of the Institute for Mathematics, Astrophysics and Particle Physics (IMAPP).

Black hole symphonies: revealing the complexities in gravitational waves

In this new work, the authors showed the presence of QNM frequencies predicted by second-order perturbation theory in the gravitational wave flux infalling into the horizon.

The observation of multiple ringdown modes in a binary black hole merger

An international team of researchers including Prof. Badri Krishnan at Radboud University has verified an important property of black holes known as the no-hair theorem using gravitational wave observations.

AI4Science Kick-off

IRP, together with Sascha Caron (IMAPP), is launching a series of events to bring together researchers utilising artificial intelligence. The goal is to create a network of researchers working together on topics related to AI within the faculty.


The High Energy Physics department explores new physics via cosmic rays at Pierre Auger, ATLAS@CERN, and neutrino projects like PTOLEMY and DUNE, using quantum and machine learning tools. We model quantum gravity to fill the Standard Model's gaps, tested by LIGO/Virgo data, anticipating future discoveries. Our scientific contributions can be found in the Publications archive in Radboud Repository.

Collider Physics

At the Collider Physics team we are active in collider-based experiments, mainly with CERN's ATLAS at the LHC, contributing notably to the Higgs boson's discovery and ongoing property studies.

Collider Physics

Cosmic Rays

The Cosmic Rays team studies ultra-high energy cosmic rays to probe the Standard Model at extreme energies, focusing on projects like the Pierre Auger Observatory and GRAND.

Cosmic Rays


The Gravity team explores gravity at all scales, focusing on Quantum Gravity to unify quantum theory with general relativity, and Strong Gravity including theoretical work, simulations of black hole mergers, and analysis of gravitational wave data.


Particle Physics Theory

The Particle Physics Theory group explores fundamental particles and their interactions, questioning the nature of dark matter, dark energy, and the universe's stability.

Particle Physics Theory


The department of High Energy Physics offers various courses in the education programmes at the Faculty of Science. It is closely involved in the Bachelor's Physics and Astronomy and the Master's specialisation Particle and Astrophysics.

PhD / Graduate school

High Energy Physics offers doctoral projects across all areas of their research specialism. It is possible to enter the graduate schools from DRSTP and OSAF. Look for research inspiration in the PhD dissertations archive in Radboud Repository.
