Week 37 at the Pole

Sunrise is slowly coming along at the South Pole, with some refracted light showing over the horizon on clear days. The impending orange glow appears to be approaching the ICL in this image. […]

A summer of Antarctic research at UWRF

The Physics Department of UW–River Falls hosts summer internships for young college students that allow them to engage in IceCube and other polar science projects. Over the 10-week internship, they become a member of the team, where they learn to program and to tackle challenging scientific questions. And, as you will read here, they also get a chance to share their experience. […]

The tau neutrino hunt is now in full swing

Today the IceCube Collaboration has presented a search for tau neutrinos at energies above 214 TeV that, although it did not find any events, allowed setting upper limits on the astrophysical tau neutrino flux. This search sets limits on tau neutrinos at energies three orders of magnitude lower than the energies reached by previous dedicated tau neutrino searches. And more importantly, the results now submitted to Physical Review D also prove that tau neutrino searches in IceCube are reaching the sensitivity for a potential discovery. […]

Week 36 at the Pole

The landscape at the South Pole continues to brighten, making it perhaps harder to ignore the extent of snow accumulation at the IceCube Lab. But snow removal wasn’t on the table last week, which was a quiet one all around for the IceCube winterovers. […]

Search for transient astrophysical neutrino emission using GeV muon neutrinos in IceCube

In a paper submitted today to the Astrophysical Journal, the IceCube Collaboration presents results of a search for astrophysical sources of transient neutrino emission using a sample of low-energy—30 to 300 GeV—muon neutrino events from DeepCore. Although no source is singled out, the study sets limits on soft-spectra models, such as energetic or nearby choked GRBs. […]

Week 35 at the Pole

Although the sunrise is still not officially here, the South Pole is enjoying a period of twilight. The horizon is clearly visible in the direction of the sun and is showing some characteristic orange color. The photo shows this nicely, with the added effect that reflection in the station windows gives the appearance of a clear view through the windows of the continuous horizon. […]

Week 34 at the Pole

The South Pole station’s windows were exposed last week, after being covered up (decoratively, we might add) for over four months now. Outside, it still looks more like night than day, but things will gradually brighten up, and then the windows might need to be covered for a different reason—to promote a better sleeping environment.
