Astroparticle physics with the neutrino telescope IceCube

IceCube is an international collaboration that built and operates an instrument of the same name for the exploration of the universe using high-energy neutrinos. For this, a volume of one cubic kilometer was instrumented with optical sensors two kilometers below the geographical South Pole. Central to the project is the question of the origin of the cosmic rays and their acceleration mechanisms. Apart from this, the physics performed with IceCube addresses a variety of other fundamental questions like in the search for dark matter or monopoles.
