Characterizing the diffuse neutrino flux with the future KM3NeT/ARCA detector

Probing Particle Physics with IceCube The IceCube observatory located at the South Pole is a cubic-kilometre optical Cherenkov telescope primarily designed for the detection of high-energy astrophysical neutrinos. IceCube became fully operational in 2010 and reached a milestone in 2013 by the first observation of cosmic neutrinos in the TeV-PeV...

On the difficulties to derive reliable CNO abundances in hot massive stars Though low in number, massive stars play an essential role in the early and present Universe, due to their enormous energy output and production of metals. Moreover, the end-products of massive star evolution are among the most spectacular...

The Magnetic Field of the Milky Way The Milky Way's magnetic field has coherent structures on Galactic scales, following spiral arms but also Galactic outflows. It also has a turbulent component, which influences the galactic ecosystem in many ways, such as delaying star formation, isotropizing Galactic cosmic rays, and providing...

Recent Results from X-ray Studies of Supernova Remnants X-ray emission from supernova remnants provides us with probes to high energy phenomena such as acceleration of cosmic-ray particles and nucleosynthesis in supernova explosions. In this talk, I will present some of recent results that I, with my students and collaborators, obtained...

Information field theory - turning data into images Charting the Universe from measurements is a challenging information theoretical problem. The finite data provided by instruments is never able to constraint the infinite degrees of freedom of the physical fields we are interested in astronomy or other areas. Additional information like...

HyperKamiokande: a next generation long baseline neutrino experiment in Japan The seminar will present the HyperKamiokande (HyperK) project which will build a large volume water Cerenkov detector for long baseline neutrino oscillation studies in Japan. A brief historical resume of the discovery of neutrino oscillations will be provided. The presentation...

Radio detection of ultra-high energy neutrinos High energy neutrino astronomy is a powerful tool to study the high-energy universe. Neutrinos can escape dense source environments and point back to their sources with sub-degree accuracy. In particular, multi-messenger analyses that combine neutrino detection with electromagnetic (e.g. gamma ray) and gravitational-wave observations...

Cosmic rays between the knee and the ankle Investigations of the energy spectrum as well as the mass composition of cosmic rays in the energy range of PeV to EeV are important for understanding both, the origin of the galactic and the extragalactic cosmic rays. The multi-detector arrangement of KASCADE...

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...
