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 The DeepCore array inside IceCube has a low-energy threshold that allows us to study neutrino oscillation properties.
	Neutrino Astronomy 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.
	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.
	GraphNeT Learn more earn more about the machine learning framework for reconstruction and classification of low-energy IceCube events GraphNeT.
	Discover The Detector Learn more about how neutrinos are detected in IceCube.

Prospective B.Sc. and M.Sc. students are encouraged to contact Jason Koskinen, koskinen@nbi.ku.dk, 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 every year in March or April: 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.

IceCube has exhibits at the reoccuring event of Kulturnatten (Copenhagen Cultural Night) at NBI.

We are happy to tell more, so please contact us.
