WELCOME TO NUSKY 2011!
 
Detection of high energy cosmic neutrinos will open a new window on the Universe and may turn out to be one of the major discoveries of this century. Study of cosmic neutrinos will provide unique and qualitatively new information about the most energetic astrophysical phenomena e.g. active galactic nuclei and gamma-ray bursts, as well as on the origin of cosmic rays, the evolution of the Universe, the nature of dark matter and other new physics beyond the Standard Model.
 
In recent years much new information has been obtained about high energy cosmic rays (from HiRes and the Pierre Auger Observatory) as well as high energy gamma-rays (from HESS, MAGIC, VERITAS, from MILAGRO, and from the Fermi satellite). This has enabled more precise prediction of expected cosmic neutrino fluxes. The construction of IceCube, the world's biggest neutrino detector, has been completed and KM3NeT is planned. New techniques for radio detection of neutrinos are being employed (ANITA) and other ambitious projects (ARIANNA, ARA) are under discussion.
 
The goal of this workshop is to bring together astrophysicists, experts in cosmic rays and neutrino physicists to discuss the status and perspectives of this field which is about to enter a very exciting phase.
