Extending the search for neutrino point sources with IceCube above the horizon
The IceCube Collaboration, R. Abbasi
Point source searches with the IceCube neutrino telescope have been restricted to one hemisphere, due to the exclusive selection of upward going events as a way of rejecting the at…
Kilometer-Scale Neutrino Detectors: First Light
Francis Halzen
This is a brief report on the status of neutrino "astronomy" at a time when the kilometer-scale neutrino detector IceCube is approaching completion. We revisit the rationale for co…
Neutrino emission from high-energy component gamma-ray bursts
J. K. Becker, F. Halzen, A. O'Murchadha +1
Gamma-ray bursts have the potential to produce the particle energies (up to eV) and the energy budget () to accommodate the spectrum of…
The Indirect Search for Dark Matter with IceCube
Francis Halzen, Dan Hooper
We revisit the prospects for IceCube and similar kilometer-scale telescopes to detect neutrinos produced by the annihilation of weakly interacting massive dark matter particles (WI…
IceCube: The Rationale for Kilometer-Scale Neutrino Detectors
Francis Halzen
At a time when IceCube is nearing completion, we revisit the rationale for constructing kilometer-scale neutrino detectors. We focus on the prospect that such observatories reveal…
Gamma-ray Astronomy with Muons: Sensitivity of IceCube to PeVatrons in the Southern Sky
Francis Halzen, Alexander Kappes, Aongus O'Murchadha
Northern hemisphere TeV gamma-ray observatories such as Milagro and Tibet AS have demonstrated the importance of all-sky instruments by discovering previously unidentified sourc…
Reconstructing the supernova bounce time with neutrinos in IceCube
Francis Halzen, Georg G. Raffelt
Generic model predictions for the early neutrino signal of a core-collapse supernova (SN) imply that IceCube can reconstruct the bounce to within about +/- 3.5 ms at 95% CL (assume…
IceCube: Neutrinos Associated with Cosmic Rays
Francis Halzen
After a brief review of the status of the kilometer-scale neutrino observatory IceCube, we discuss the prospect that such detectors discover the still-enigmatic sources of cosmic r…
First Neutrino Point-Source Results From the 22-String IceCube Detector
IceCube Collaboration, R. Abbasi
We present new results of searches for neutrino point sources in the northern sky, using data recorded in 2007-08 with 22 strings of the IceCube detector (approximately one-fourth…
IceRay: An IceCube-centered Radio-Cherenkov GZK Neutrino Detector
P. Allison, J. Beatty, P. Chen +18
We discuss design considerations and simulation results for IceRay, a proposed large-scale ultra-high energy (UHE) neutrino detector at the South Pole. The array is designed to det…
Multi-Messenger Astronomy with GRBs: A White Paper for the Astro2010 Decadal Survey
Michael Stamatikos, Neil Gehrels, Francis Halzen +2
Gamma-ray Bursts (GRBs) are relativistic cosmological beacons of transient high energy radiation whose afterglows span the electromagnetic spectrum. Theoretical expectations of cor…
Identifying Galactic PeVatrons with Neutrinos
M. C. Gonzalez-Garcia, Francis Halzen, Soumya Mohapatra
We perform a realistic evaluation of the potential of IceCube, a kilometer-scale neutrino detector under construction at the South Pole, to detect neutrinos in the direction of the…
Determination of the Atmospheric Neutrino Flux and Searches for New Physics with AMANDA-II
The IceCube Collaboration
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 ene…
Search for high-energy muon neutrinos from the "naked-eye" GRB 080319B with the IceCube neutrino telescope
IceCube Collaboration, R. Abbasi
We report on a search with the IceCube detector for high-energy muon neutrinos from GRB 080319B, one of the brightest gamma-ray bursts (GRBs) ever observed. The fireball model pred…
