99. Searches for Point and Extended Sources of Neutrinos with the IceCube Detector

Observing a neutrino point source would be a “smoking gun” signature of a cosmic ray accelerator. Here we present searches for time-independent neutrino emission from astrophysical sources using the IceCube detector. The analyses use data collected during the first four years of detector operation. An unbinned maximum likelihood method is used to search for individual point sources, spatially...

100. Search for Neutrinos form Gamma-Ray Bursts with ANTARES

ANTARES is the largest high-energy neutrino telescope on the Northern Hemisphere. Its main scientific purpose is the search for astrophysical muon neutrinos that are detected via their charged-current interaction in Earth and the subsequent Cherenkov emission of the secondary muon in the water of the Mediterranean Sea. Among the most promising candidates are gamma-ray bursts, as they are...

101. Search for Prompt Neutrino Emission from Gamma Ray Bursts with IceCube

IceCube is the first neutrino telescope with TeV-PeV sensitivity sufficient to constrain the prompt neutrino flux from Gamma Ray Bursts (GRBs). Limits based on data from the 40- and 59-string partially completed detector configurations have been published previously. Much of the parameter space for the previous generation of neutrino fluence models was excluded, which has encouraged continued...

102. Search for correlation of high-energy starting events in IceCube with GRBs

IceCube is a cubic kilometer detector operating at the geographical South Pole. IceCube is sensitive to very-high-energy neutrinos. IceCube has reported evidence for the observation of astrophysical neutrinos in a set of 28 events collected between May 2010 and May 2012 with energies ranging from ~30 TeV to ~1.2 PeV. We present here the current status of a study of the temporal and spatial...

103. Demystifying the PeV Cascades in IceCube: Less (Energy) is More (Events)

The IceCube neutrino observatory has detected two cascade events with energies near 1 PeV. Without invoking new physics, we analyze the source of these neutrinos. We show that atmospheric conventional neutrinos and cosmogenic neutrinos (those produced in the propagation of ultra-high- energy cosmic rays) are strongly disfavored. For atmospheric prompt neutrinos or a diffuse back- ground of...

106. Performance of the ARIANNA Neutrino Telescope

Part of a new generation of neutrino telescopes, the ARIANNA experiment uses low noise, low power and inexpensive technology to search for extremely high energy cosmic neutrinos. The telescope measures the intense radio pulse emitted by the charged particle showers resulting from neutrino interactions in the Ross Ice Shelf of Antarctica. Four stations have been installed in the ice to take...

107. Reconstructing Askaryan Electric Fields in ARIANNA

The Antarctic Ross Ice Shelf Antenna Neutrino Array (ARIANNA) is an ultra-high energy neutrino detector currently under construction in Moore's Bay, in Western Antarctica. ARIANNA is designed to trigger upon and digitize GHz radio-frequency (RF) pulses created by neutrino interactions, via the Askaryan effect. In order to reconstruct the distinctive shape of this electric field, the...

108. PRIDE – Passive Radio Ice Depth Experiment - An Instrument to Measure Outer Planet Lunar Ice Depths from Orbit using Neutrinos

Tim Miller

26/08/2013, 18:06

We describe a novel application of extreme high energy neutrino detection: a concept for an instrument to measure the thickness of the ice shell on a planetary body, such as Jupiter’s moon Europa, by making use of the Askaryan Effect RF signal from EHE neutrinos. Unlike the current most often considered approach to measuring outer planetary moon ice sheet thickness, a large high powered active...
