Improvement in fast particle track reconstruction with robust statistics

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

The IceCube project has transformed 1 km(3) of deep natural Antarctic ice into a Cherenkov detector Muon neutrinos are detected and their direction is inferred by mapping the light produced by the secondary muon track inside the volume instrumented with ph ...

Observation of the cosmic-ray shadow of the Moon with IceCube

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

We report on the observation of a significant deficit of cosmic rays from the direction of the Moon with the IceCube detector. The study of this "Moon shadow" is used to characterize the angular resolution and absolute pointing capabilities of the detector ...

Search for non-relativistic magnetic monopoles with IceCube

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

The IceCube Neutrino Observatory is a large Cherenkov detector instrumenting of Antarctic ice. The detector can be used to search for signatures of particle physics beyond the Standard Model. Here, we describe the search for non-relativistic, magnetic mono ...

Measurement of Atmospheric Neutrino Oscillations with IceCube

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

We present the first statistically significant detection of neutrino oscillations in the high-energy regime (> 20 GeV) from an analysis of IceCube Neutrino Observatory data collected in 2010 and 2011. This measurement is made possible by the low-energy thr ...

IceTop: The surface component of IceCube

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

IceTop, the surface component of the IceCube Neutrino Observatory at the South Pole, is an air shower array with an area of 1 km(2). The detector allows a detailed exploration of the mass composition of primary cosmic rays in the energy range from about 10 ...

Search for Dark Matter Annihilations in the Sun with the 79-String IceCube Detector

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

We have performed a search for muon neutrinos from dark matter annihilation in the center of the Sun with the 79-string configuration of the IceCube neutrino telescope. For the first time, the DeepCore subarray is included in the analysis, lowering the ene ...

First Observation of PeV-Energy Neutrinos with IceCube

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

We report on the observation of two neutrino-induced events which have an estimated deposited energy in the IceCube detector of 1.04 +/- 0.16 and 1.14 +/- 0.17 PeV, respectively, the highest neutrino energies observed so far. These events are consistent wi ...

We have searched for extremely high energy neutrinos using data taken with the IceCube detector between May 2010 and May 2012. Two neutrino-induced particle shower events with energies around 1 PeV were observed, as reported previously. In this work, we in ...

We present the results of a first search for self-annihilating dark matter in nearby galaxies and galaxy clusters using a sample of high-energy neutrinos acquired in 339.8 days of live time during 2009/10 with the IceCube neutrino observatory in its 59-str ...
