Search for a diffuse flux of astrophysical muon neutrinos with the IceCube 59-string configuration

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

A search for high-energy neutrinos was performed using data collected by the IceCube Neutrino Observatory from May 2009 to May 2010, when the array was running in its 59-string configuration. The data sample was optimized to contain muon neutrino induced e ...

Search for neutrino-induced particle showers with IceCube-40

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

We report on the search for neutrino-induced particle showers, so-called cascades, in the IceCube-40 detector. The data for this search were collected between April 2008 and May 2009 when the first 40 IceCube strings were deployed and operational. Three co ...

IceCube search for dark matter annihilation in nearby galaxies and galaxy clusters

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

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 ...

Search for Time-dependent Neutrino Emission from Astrophysical Sources with 3 yr of IceCube Data

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

We present the results of a search for neutrino point sources using the IceCube data collected between 2008 April and 2011 May with three partially completed configurations of the detector: the 40-, 59-, and 79-string configurations. The live-time of this ...

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 ...

Probing the origin of cosmic rays with extremely high energy neutrinos using the IceCube Observatory

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

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 ...
