IceCube Experiment

The IceCube Neutrino Observatory, embedded down to 2.5 km deep under the South Pole, is the world's largest and most sensitive ‘telescope' for high energy neutrinos. With a cubic kilometer of instrumented ice it is the largest particle detector in the world.

IceCube is a part of the subatomic group at the Niels Bohr Institute. The group includes both experimentalists and theorists (from the Niels Bohr International Academy). Indicated are selected topics of responsibility or research interests within neutrino physics and IceCube.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

IceCube is a polyvalent detector that is well suited for many different areas of research. Our local group at NBI is focusing its efforts in two main areas: low-energy neutrino oscillations, and high-energy astroparticle physics.

Neutrino Oscillations
Neutrino oscillations
The DeepCore array inside IceCube has a low-energy threshold that allows us to study neutrino oscillation properties.
Neutrino Astronomy
Neutrino Astronomy
This area of research includes searches for neutrino sources, and progenitors of ultra-high-energy cosmic rays (UHECR).
Dark Matter
Dark Matter (DM) Searches
Many theories describing DM candidates predict that they can annihilate into detectable neutrinos.
The IceCube upgrades The IceCube Upgrade
Work is underway to develop the software and analysis tools needed for a new extension of IceCube, to be deployed in 2022/2023.
