Measurement of the cosmic ray energy spectrum with IceTop-73

Shirit Cohen, Mathieu Ribordy, Matthias Wolf, Sofia Vallecorsa, Xiaoxia Bai

We report on the measurement of the all-particle cosmic ray energy spectrum with the IceTop air shower array in the energy range from 1.58 PeV to 1.26 EeV. The IceTop air shower array is the surface component of the IceCube Neutrino Observatory at the geog ...

Background studies for acoustic neutrino detection at the South Pole

Shirit Cohen, Mathieu Ribordy, Matthias Wolf, Xiaoxia Bai

The detection of acoustic signals from ultra-high energy neutrino interactions is a promising method to measure the flux of cosmogenic neutrinos expected on Earth. The energy threshold for this process depends strongly on the absolute noise level in the ta ...

Search for relativistic magnetic monopoles with the AMANDA-II neutrino telescope

Shirit Cohen, Mathieu Ribordy, Matthias Wolf, Xiaoxia Bai

We present the search for Cherenkov signatures from relativistic magnetic monopoles in data taken with the AMANDA-II detector, a neutrino telescope deployed in the Antarctic ice cap at the Geographic South Pole. The non-observation of a monopole signal in ...

Determination of the atmospheric neutrino flux and searches for new physics with AMANDA-II

Shirit Cohen, Mathieu Ribordy, Levent Demirörs, Xiaoxia Bai

The AMANDA-II detector, operating since 2000 in the deep ice at the geographic South Pole, has accumulated a large sample of atmospheric muon neutrinos in the 100 GeV to 10 TeV energy range. The zenith angle and energy distribution of these events can be u ...
