Recent results from IceCube and the future of neutrino astronomy at the South Pole The IceCube neutrino observatory at the geographic South Pole has now been operating at full capacity for ten years. Following the first observation of astrophysical neutrinos in the TeV -- PeV energy range in 2013, cosmic...
Origin of UHECR: current status of a decades-long open question Ultra-high-energy cosmic rays (UHECR) are the most energetic known particles of the Universe, being accelerated to energies up to 7 orders of magnitude higher than those achieved in human-made accelerators. Their origins, however, remain an intriguing puzzle even decades after...
Light-Shining-Through-A-Wall: The ALPS II experiment at DESY The ALPS II at DESY in Hamburg is a light-shining-through-a-wall (LSW) experiment searching for axion-like elementary particles in the sub eV mass range, which are motivated by astrophysics and cosmology. ALPS II aims at an axion-photon coupling sensitivity which is several orders of...
