In May 2013, the IceCube Collaboration elected Professor Olga Botner of Uppsala University, Sweden, as its new spokesperson, following a two-year service by Professor Greg Sullivan from the University of Maryland. […]

Week 34 at the Pole
The sun has not officially risen at the Pole yet, but things do keep getting brighter. Outside that is. Inside? Well, maybe thoughts of the sun’s arrival led to thoughts of summer foods. […]
An improved muon track reconstruction in IceCube
A new study by the IceCube Collaboration shows that the muon track reconstruction performed in the early stages of the analysis can be significantly improved by using robust statistical methods to estimate particle trajectories through the detector. The new algorithm results in a 13% gain in the angular resolution of the muon track and a 98% accuracy rate in determining the number of muons in coincident events. The paper has just been submitted to Nuclear Instruments and Methods in Physics Research Section A. […]
Week 33 at the Pole
The yellow light cast on the ground makes the scene look almost like a sandy beach, with a shorefront edging into dark waters. But it’s just an illusion, we’re still at the Pole. That’s SPTR-2, one of the South Pole satellite domes. […]
Early IceCube Tests: Greenland, 1990
Before there was IceCube, there was AMANDA, and before there was AMANDA, there were a couple people testing the idea for an in-ice neutrino detector in Greenland. […]
Week 32 at the Pole
It’s still dark at the Pole these days, but knowing that the sunrise is not that far off, station staff are taking every opportunity to capture some great night photos. […]
Week 31 at the Pole
A failed Acopian power supply is on the table for investigation. The IceCube winterovers have a broad range of job duties, but of course maintaining (and fixing if necessary) all of the computer hardware involved in collecting data from the detector is a high priority task. […]
Week 30 at the Pole
Since December is a summer month in the Southern Hemisphere, many countries like Australia and New Zealand hold Christmas in July events in order to have a Christmas with a wintry feel. They were celebrating Christmas in July at the Pole last week, but of course their climate is always wintry so maybe it was just an excuse to bake some sweet treats. […]
Week 29 at the Pole
The South Pole has been described as an otherworldly place. So it’s befitting for those working there to take a moment once in a while to just sit and contemplate their surroundings. Especially when there’s some natural light to see by—the moon can really light the place up. […]
Search for neutrino emission from astrophysical sources with IceCube
A search for neutrino point sources using throughgoing muons in IceCube has not found any excess of neutrinos above the atmospheric background in any given direction in the sky. Neither did dedicated searches of a priori selected objects. However, IceCube data provide insights into the nature of cosmic ray sources even from non-discovery results. These results have been submitted today to The Astrophysical Journal. […]
