On Sunday, June 5, IceCube will be part of the “take over” of Washington Square Park for Street Science, a free World Science Festival event. Dozens of research groups are offering hands-on activities, demonstrations, and exhibits to engage curious visitors of all ages. […]
The IceCube Collaboration presents a new search for dark matter annihilation from the galactic center and halo using cascade events, i.e., particle showers created by the interaction of electron and tau neutrinos and Z-boson mediated muon neutrinos. Scientists searched for interactions starting in the DeepCore subarray between May 2011 and May 2012 and found no neutrino excess with respect to the background-only hypothesis, which allowed them to derive upper limits on dark matter candidates with masses between 30 GeV and 10 TeV. These results have been submitted today to the European Physical Journal C. […]
Space: the final frontier. These are the images of IceCube winterover Mack van Rossem. Well, he’s not in space, and he may not exactly be “boldly going where no man has gone before,” but he is spending a year in one of the most remote locations on Earth—the South Pole. […]
“On behalf of the operations group, I’m happy to report that as of run 127950 on 2016-05-20, 20:38:47 UTC, we have started the IC86-2016 physics run.” With these words, every IceCuber learned that we were entering a new year of data for IceCube. […]
Not a particularly busy or hectic week at the Pole—quiet punctuated by work, or work punctuated by quiet, depending on how you look at things. Now, depending on where, not how, you’re looking, you get to see where the action is this time of year at the South Pole. […]
Under a sky lit by auroras, you can see the path through the Dark Sector, bright enough to make out the flag line for quite a ways into the distance. It’s a different story when there are no auroras or bright moon to illuminate things. […]
It’s aurora season at the South Pole. Two lone figures—both of IceCube’s winterovers—were out on the ice capturing images of the night sky. Although it’s a night sky, that tells us nothing about what time of day it is since it’s winter there and the sun remains down for about six months at a stretch. […]
The IceCube Collaboration has performed two independent searches for light sterile neutrinos, both with one year of data, searching for sterile neutrinos in the energy range between approximately 320 GeV and 20 TeV. IceCube has not found any anomalous disappearance of muon neutrinos and has placed new exclusion limits on the parameter space of the 3+1 model, a scenario with only one sterile neutrino. These results have been submitted today to Physical Review Letters. […]
IceCube winterover Mack’s Ecuadorian devil’s mask looks extra devilish under the red lights as he stands for a photo in his cold weather gear after coming in from outside. […]
Today, the IceCube Collaboration presents a new technique to lower the energy threshold for neutrino detection while keeping a pointing resolution to within less than a degree. IceCube researchers have used this technique in a joint search with data from a previous analysis using throughgoing muon neutrinos. No point source has been found, but sensitivity for searches below 100 TeV has been improved by a factor of ten. […]
