Dark Matter makes up more than a quarter of all matter and energy in the Universe; yet, we know very little about it. It seems that dark matter clumps in specific pockets of space, like the centers of galaxies, including the Milky Way; and it has gravitational effects on the visible matter that surrounds it. With IceCube, we can use neutrinos to search for dark matter indirectly.

The IceCube Neutrino Observatory has opened a new window towards the high-energy Universe. IceCube has collected neutrino events up to 10 PeV in energy, the highest energy neutrinos ever observed. Yet the sources of these neutrinos remain elusive. At ULB-IceCube group we are focused on the search for neutrino sources from a multi-messenger perspective.

While IceCube has not observed neutrinos with energies higher than 10 PeV, the search for PeV cosmogenic neutrinos, and the confirmation of a possible cutoff on the astrophysical neutrino spectrum, continues. One project seeking to explore the high energy regime is the IceCube Gen2, an extension of roughly an order of magnitude. In the near future RNO-G is seeking to install a radio neutrino detector in Greenland.
