Research group IceCube - Neutrino Astronomy at the South Pole
As members of the IceCube Collaboration, we use the IceCube Neutrino Observatory at the South Pole to study the most extreme processes in the Universe and to search for new physics.
The IceCube Laboratory (ICL), beneath the Milky Way. The ICL is the central point for communicating with the full array of sensors deep in the glacier.
IceCube is the first cubic-kilometre neutrino detector, buried deep in the Antarctic glacier. It consists of over 5000 optical sensors distributed over a square kilometer of area and between 1.5 and 2.5 km deep in the ice. The sensors record the faint flashes of light produced when neutrinos interact in the ice.
In 2013, IceCube announced the discovery of high-energy astrophysical neutrinos. The breakthrough paved the way for further discoveries, including neutrinos from our own galaxy the Milky Way, and evidence of ''hidden sources" like the galaxy NGC 1068 from which neutrinos escape while much of the light is blocked. During 2025-2026, construction of the IceCube Upgrade added five new detector strings with novel optical sensors and calibration devices, which will allow more precise measurements of neutrino properties.
Research of the IceCube group at Stockholm University
Our research activity is currently focused in the following areas:
- Neutrino astronomy: identifying and studying the sources of high-energy astrophysical neutrinos within and beyond our galaxy
- Searches for physics beyond the Standard Model, including particles that have not been seen before
- Design and construction of optical sensors for IceCube
- Advanced application of machine learning to IceCube data
Our group is part of the Oskar Klein Centre for Cosmoparticle Physics. The OKC is an environment that brings together particle physicists and astrophysicists, experimentalists and theorists, from Stockholm University and the KTH Royal Institute of Technology.
