Indirect Dark Matter Searches and Cosmic Ray Transport in the Era of AMS The Alpha Magnetic Spectrometer (AMS) is installed on the International Space Station (ISS) since May 2011. AMS is a complex particle detector designed to precisely measure the fluxes of cosmic rays between 0.5 GeV and a few TeV. The physics goals of the experiment include the search for possible signals of dark matter annihilation and hints for primordial antimatter in the fluxes of cosmic rays. As of…

High-energy neutrinos from AGN? With the advent of multi-messenger observatories, neutrino astronomy is turning into a helpful tool to investigate and put limits on the contribution of the known astrophysical objects to the diffuse neutrino background. Active Galactic Nuclei (AGN) have long been suggested among the candidate sources of cosmic high-energy neutrinos. If hadronic processes operate in the AGN jets, a lot can be learnt by combining neutrino observations with the putative accompanying electromagnetic information. This is motivated by the…
