Galactic and extragalactic contributions to the astrophysical neutrino flux

Spectral and anisotropy properties of IceCube astrophysical neutrino signals reveal evidence for a sizeable Galactic contribution to the neutrino flux in the Southern Hemisphere. I will review this evidence and relate it to the absence of Galactic component signature in the muon neutrino signal from the Northern sky. I will discuss implications of the possible Galactic component of the astrophysical neutrino flux for understanding of the cosmic ray content of the Milky Way and of the locally observed cosmic ray flux. I will also review possible options for the extragalactic astrophysical neutrino flux component which presumably dominates the signal in the Northern hemisphere.

GRB observations at High and Very High Energy

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 observational properties of the detected bursts and their main theoretical interpretations.

At very high energies (E>100 GeV) the detection of GRBs by currently operating Imaging Atmospheric Cherenkov telescopes is still missing. Based on the observation of GRBs at lower energies, I will discuss the prospects of GRB detection by future VHE facilities, like the Cherenkov Telescope Array.
