We apply for the Swedish contribution to M&O costs for IceCube for the years 2019 -2023. The application is a continuation of the operations grant VR 821-2013-1673. The annual contribution rate has been determined by IceCube’s International Oversight and Finance Group where Sweden is represented by VR. IceCube is the world’s largest neutrino telescope embedded in the clear glacier ice at the South Pole, designed to detect high-energy neutrino radiation from cosmic sources. In 2013, IceCube discovered high-energy neutrinos of extraterrestrial origin. This represents a breakthrough and opens the path towards neutrino astronomy. Neutrino emission is predicted in models of the mechanisms powering active galaxies and for processes causing gamma ray bursts. The design of the telescope also allows research into other topics, like searches for dark matter, studies of neutrino properties, searches for neutrinos from supernova explosions within the Milky Way and studies of cosmic ray anisotropies. The Swedish groups in Stockholm and Uppsala have been involved in the development of ice-based neutrino detectors from the very outset i.e. for more than 20 years, taking part in the AMANDA project, which proved that the concept of an ice-based neutrino observatory is viable. AMANDA was the prototype for the much larger IceCube array, which was completed in December 2010 and is now producing competitive results.
