IceCube is a cubic kilometer scale, deep-ice Cherenkov neutrino
detector at the South Pole. IceCube’s cosmic neutrino searches cover
an energy region all the way from below TeV to EeV and higher. In the
EeV energy region, a flux of 'cosmogenic' neutrinos generated by
interactions of ultra-high energy cosmic rays on intervening radiatio
backgrounds is expected. We have analysed 7 years of...
In the transient sky are found the most violent phenomena in the universe. These phenomena are the best known spots to supply enough energy and flux to ultrahigh energy astroparticles at the observed level. In this talk, we will focus on some of these powerful objects (e.g., gamma-ray bursts, young pulsars, magnetars, superluminous supernovae, black hole mergers) and estimate their expected...
Cosmogenic UHE neutrino fluxes are discussed. These fluxes can be detectable by Ice- Cube and future big neutrino detectors only in case the primary UHECR flux is proton dominated. The strong upper limit on proton component of UHECR is given by diffuse flux of HE photons measured recently by Fermi LAT detector up to energy 1 TeV. We argue that this limit still allows the proton-dominated...
