An absence of neutrinos associated with cosmic-ray acceleration in γ-ray bursts

Rasha Abbasi, +269 more
- 18 Apr 2012 - 
TL;DR: An upper limit on the flux of energetic neutrinos associated with GRBs that is at least a factor of 3.7 below the predictions is reported, implying either that GRBs are not the only sources of cosmic rays with energies exceeding 1018 electronvolts or that the efficiency of neutrino production is much lower than has been predicted.
Journal ArticleDOI

The design and performance of IceCube DeepCore

Rasha Abbasi, +268 more
TL;DR: DeepCore as discussed by the authors was designed to lower the IceCube neutrino energy threshold by over an order of magnitude, to energies as low as about 10 GeV. DeepCore is situated primarily 2100 m below the surface of the icecap at the South Pole, at the bottom center of the existing IceCube array, and began taking physics data in May 2010.
Journal ArticleDOI

Calibration and Characterization of the IceCube Photomultiplier Tube

Rasha Abbasi, +263 more
TL;DR: In this paper, the authors describe the laboratory characterization and calibration of the 10-in. diameter R7081-02 made by Hamamatsu Photonics before deployment of the IceCube neutrino observatory.
Journal ArticleDOI

Measurement of the atmospheric neutrino energy spectrum from 100 GeV to 400 TeV with IceCube

Rasha Abbasi, +267 more
- 05 Jan 2011 - 
TL;DR: In this paper, a measurement of the atmospheric muon neutrino energy spectrum from 100 GeV to 400 TeV was performed using a data sample of about 18, 000 up-going atmospheric neutrinos events in IceCube.
Journal ArticleDOI

Limits on a Muon Flux from Neutralino Annihilations in the Sun with the IceCube 22-String Detector

Rasha Abbasi, +258 more
TL;DR: In this paper, a search for neutrinos from neutralino annihilations in the Sun has been performed with the IceCube 22-string neutrino detector using data collected in 1043 days of live time in 2007 No excess over the expected atmospheric background has been observed.
