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, based in the Discovery Center. 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.
About the IceCube group at NBI
The IceCube group at the Niels Bohr Institute is engaged with both the experimental and theoretical side of neutrino physics and astrophysics, being embedded within the Discovery Center and involving theorists from the Niels Bohr International Academy.
IceCube members at NBI have a broad science portfolio: from searches for high-energy neutrinos from the most violent astrophysical phenomena in the universe such as gamma-ray bursts, supernovae, active galactic nuclei, etc, to fundamental physics probes of quantum mechanical neutrino oscillations and searches for dark matter.
NBI's participation in IceCube was made possible through the support of the Danish National Research Foundation and members of the IceCube groups are also supported by the Villum Foundation, and the Carlsberg Foundation.
About the IceCube Collaboration
Since 2013 NBI has been a full member of the IceCube Collaboration, which includes over 300 scientists from 49 institutions in 12 countries.
The full list of collaborating institutions is available on the IceCube collaboration website
Research at the IceCube Neutrino Observatory
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.
The DeepCore array inside IceCube has a low-energy threshold that allows us to study neutrino oscillation properties.
This area of research includes searches for neutrino sources, and progenitors of ultra-high-energy cosmic rays (UHECR).
|Dark Matter (DM) Searches
Many theories describing DM candidates predict that they can annihilate into detectable neutrinos.

Prospective B.Sc. and M.Sc. students are encouraged to contact Jason Koskinen, firstname.lastname@example.org, regarding working with the NBI IceCube group and possible Projects.
The IceCube group is engaged in mulitiple outreach projects, and we always welcome groups of interested people to learn more about this fascinating experiment.
Interact with IceCube
Any interested groups are encouraged to contact us regarding activities/events related to IceCube and neutrinos. We can come to you, or you can come to us!
High school classes are always welcome to apply for lectures/activities.
High school students are invited to individually to join the international IceCube MasterClass on March 11th, 2019: Spend a full day at the Niels Bohr Institute, analyse real data from IceCube to discover astrophysical neutrinos, and discussing physics with researchers from IceCube.
The international IceCube MasterClass at NBI in 2015 was a huge succes, and attracted enthusiastic students from all over the country.
IceCube has exhibits at the reoccuring event of Kulturnatten (Copenhagen Cultural Night) at NBI.
We are happy to tell more, so please contact us.
