نویسنده
چکیده
Based on combined 3-year data, the IceCube collaboration has reported recently the discovery of a diffuse background of high energy (HE) astrophysical neutrinos with energy above 60 TeV that extends at least up to 3 PeV, in excess (5.7σ significance level) of that produced by cosmic ray (CR) interactions in the atmosphere. The neutrino events did not point back to any identified sources and are consistent with an isotropic distribution of arrival directions. Their best fit power-law to the energy flux per flavor above 60 TeV is

The origin of galactic cosmic rays is one of the most interesting unsolved problems in astroparticle physics. Experimentally, the problem is attacked by a multi-disciplinary effort, namely by direct measurements of cosmic rays above the atmosphere, by air shower observations, and by the detection of TeV γ rays. Recent experimental results are presented and their implications on the contemporary...

The Alpha Magnetic Spectrometer (AMS), whose final version AMS-02 is to be installed on the International Space Station (ISS) for at least 3 years, is a detector designed to measure charged cosmic ray spectra with energies up to the TeV region and with high energy photon detection capability up to a few hundred GeV, using state-of-the-art particle identification techniques. Following the succes...

The acceleration of the cosmic expansion is a fundamental challenge to standard models of particle physics and cosmology. The new physics of dark energy may lie in the nature of gravity, the quantum vacuum, or extra dimensions. I give a brief overview of the puzzles and possibilities of dark energy, and discuss the confrontation of a wide variety of “beyond Einstein” models with the latest data...
