Observing astrophysical neutrinos can provide a unique insight into the acceleration mechanism of cosmic ray sources: because neutrinos should be produced in hadronic interactions and are neither absorbed nor deflected they point directly back to their sources. This talk will cover recent searches in IceCube for high-energy neutrinos (> 100 TeV), which have produced the first evidence for a...

The IceCube Neutrino Observatory is the largest operating experiment searching for astrophysical neutrinos. Situated at the geographical South Pole, IceCube has been completed in 2010 and is entering its phase of discovery now. Several studies that have recently been performed in IceCube show an excess of events at high energies, indicating the presence of a non-atmospheric component in the...

Neutrinos play important roles in revealing energetic astrophysical explosions such as gamma-ray bursts (GRBs) and supernovae (SNe). The large neutrino detector, IceCube has opened a new window of the multi-messenger astronomy.
I discuss neutrino emissions from GRBs in view of recent theoretical/observational progress, and emphasize the importance of sub-TeV neutrino astronomy. In...

The Pierre Auger Observatory detects the most energetic cosmic rays using two complementary detection techniques, fluorescence telescopes and a ground array of particle detectors. The fluorescence telescopes operate during night time and they are able to map the longitudinal profile of the air shower. The atmospheric depth at which an air shower reaches its maximum size (Xmax) is correlated...

The characteristics of extensive air showers (EAS) are sensitive to the details of hadronic interactions at energies and kinematic regions beyond those tested by man-made accelerators. Uncertainties on extrapolations of the hadronic interaction models in these regions hamper the interpretation of the ultra high energy cosmic ray data in terms of primary mass composition. We report on how the...
