SUMMARY:ECAP Seminar: Alexander Kappes
DESCRIPTION:Recent results from IceCube and the future of neutrino astronomy at the South Pole\nThe 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 neutrinos have been established as an important information carrier for exploring the high-energy universe in the context of multi-messenger observations. However\, despite a first compelling evidence\, the sources of high-energy neutrinos remain largely hidden\, indicating a complex neutrino sky.\nAfter an introduction to neutrino astronomy as well as the operation principle of neutrino telescopes and the challenges of building a neutrino detector at the South Pole\, the talk will highlight recent results from IceCube. Finally\, an outlook on future enhancements of IceCube is given\, which aim at addressing the open questions.

SUMMARY:ECAP Seminar: Rodrigo Guedes Lang
DESCRIPTION:Origin of UHECR: current status of a decades-long open question\nUltra-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 their discovery. In this seminar\, the current status of this puzzle will be discussed. The state-of-the-art experiments will be presented as well as a compilation of relevant data collected so far. The power and limitations of phenomenological studies to decipher this question will be discussed\, focusing on models to estimate the role of local UHECR sources.

SUMMARY:ECAP Seminar: Katharina-Sophie Isleif
DESCRIPTION:Light-Shining-Through-A-Wall: The ALPS II experiment at DESY\nThe 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 magnitude better than that of previous LSW experiments and will thus investigate a new parameter range. This is achieved by an increased magnetic field interaction length and by optical cavities on both sides of the wall\, which further amplify the signal.\nIn this talk\, the working principle of LSW experiments and the uniqueness and technological challenges of the ALPS II experiment will be explained. Interim results of previous investigations will be presented\, as well as the current status. By converting axions to photons\, we expect a rate of only 1 photon per day. The two sophisticated detector schemes\, coherent heterodyne detection and a cryogenic single photon detector\, are also presented and their implementation in the ALPS II experiment is discussed. ALPS II is aiming at a first data run in late 2021.
