Atmospheric neutrino oscillations measured with three years of IceCube data

Posted on October 28, 2014 by Silvia Bravo

Last year, an initial measurement of the neutrino oscillation parameters was a hint that IceCube could become an important detector for studying neutrino oscillations. Today, the IceCube Collaboration has submitted new results to Physical Review Letters that present an improved measurement of the oscillation parameters, via atmospheric muon neutrino disappearance, which is compatible and comparable in precision to those of dedicated oscillation experiments such as MINOS, T2K or Super-Kamiokande.

Week 41 at the Pole

Posted on October 27, 2014 by Jean DeMerit

After the sun’s arrival come the planes. The first of the season to reach the South Pole were a pair of Twin Otters, one of which appears parked in the accompanying image. Behind it is a Basler plane—a somewhat larger ski aircraft—shown just as it was landing, a few days later. […]

Week 40 at the Pole

Water restrictions prompt innovation. When already limited showers get rationed even further, as they have been recently at the South Pole station, you start thinking of ways to work around the problem. […]

UW physicist Francis Halzen receives American Ingenuity Award

Posted on October 17, 2014 by Staff

Francis Halzen, the University of Wisconsin-Madison physicist who was the driving force behind the giant neutrino telescope known as IceCube at the South Pole, has been named a winner of the 2014 American Ingenuity Award. […]

Week 39 at the Pole

Ah, the things we take for granted. Sunshine might be one of them. Running water might be another. At the Pole, sometimes you have to do without. […]

More on astrophysical neutrinos yet no track of charmed mesons

Posted on October 7, 2014 by Silvia Bravo

The IceCube Collaboration has expanded the search for neutrino interactions in IceCube, lowering the range of deposited energy down to 1 TeV. The goal was a better understanding of the different contributions to the neutrino flux in IceCube and hopefully to measure the charmed-meson component for the first time. The results of this study have been submitted today to Physical Review D. […]

Week 38 at the Pole

Posted on October 7, 2014 by Jean DeMerit

Now that the sun is back at the South Pole, there’s nowhere to hide. You can walk outside and see everything—everything that was there in the darkness all winter long, like buildings and fixed structures, as well as other things that weren’t there but have recently reappeared, like the flags at the ceremonial pole. […]

Week 37 at the Pole

Posted on October 1, 2014 by Jean DeMerit

After months and months of darkness, it’s no wonder that the sun’s return to the South Pole is anxiously awaited. Finally, thanks to sufficient ambient light levels, the current winterovers can get a nice group photo outside. […]

Week 36 at the Pole

Posted on September 25, 2014 by Jean DeMerit

As dawn approaches, the sky is cast in a glow that reflects off the sides of the South Pole station. Inside the station, they’ve begun to remove the window covers that remain in place all winter, there to minimize light pollution for sensitive experiments at the Pole. […]
