Gamma Ray Bursts are among the most powerful astrophysical phenomena. In the recent past many observations shed light on their high-energy (HE, E>10 MeV) emission properties. In the seminar I will describe the observations of GRBs by the currently operating HE satellites AGILE and Fermi. I will discuss the main...
The arrival directions of Galactic cosmic rays are highly isotropic. This is expected from the presence of turbulent magnetic fields in our Galactic environment that repeatedly scatter charged cosmic rays during propagation. However, various cosmic ray observatories have identified weak anisotropies of various angular sizes and with relative intensities of...
Driven by the profound evidence from cosmology and astronomy the existence of dark matter is well-established as a part of our universe. Despite the fact, that there is five times more dark matter than baryonic matter out in the universe, its nature remains puzzling up to now. The promising idea...
The High-Altitude Water Cherenkov Observatory (HAWC) collected more than a year of data in its full configuration. With its large field of view and high uptime it is exposed to two-thirds of the sky every day. From the light distribution in the arrays water-Cherenkov tanks we discriminate between electromagnetic and...
The Jiangmen Underground Neutrino Observatory (JUNO) is a neutrino experiment under construction near Jiangmen, China. Its main component will be a spherical 20 kton liquid scintillator detector placed in a 700 m deep underground laboratory. The experiment is designed for the determination of the neutrino mass hierarchy by measuring oscillation...
