Last week was relatively quiet at the Pole. IceCube’s winterovers performed a few detector maintenance tasks and gave a tour of the ICL to South Pole logistics personnel. Although winter is fast approaching and the sun is quite low, there is still plenty of daylight for taking outdoor photos. Above we see the tour group […]
The sun is getting noticeably lower in the sky at the South Pole. IceCube’s winterovers also note that it’s starting to get cold. Apparently, there’s “cold” and then there’s “South Pole cold.” Last week, the winterovers were busy outdoors, taking advantage of the lingering light to complete a round of IceTop snow measurements. They also […]
On December 8, 2016,* a high-energy particle called an electron antineutrino hurtled to Earth from outer space at close to the speed of light carrying 6.3 petaelectronvolts (PeV) of energy. Deep inside the ice sheet at the South Pole, it smashed into an electron and produced a particle that quickly decayed into a shower of […]
On December 8, 2016, IceCube saw a Glashow resonance event, a phenomenon predicted by Nobel laureate physicist Sheldon Glashow in 1960. With this detection, scientists provided another confirmation of the Standard Model of particle physics. It also further demonstrated the ability of IceCube, which detects nearly massless particles called neutrinos using thousands of sensors embedded […]
Introduction This data release accompanies results published in Nature describing detection of the first candidate Glashow resonance event. The event was found to have a reconstructed visible energy of 6.05 ± 0.72 PeV, consistent with an electron antineutrino interacting via the Glashow resonance. In addition, early pulses were detected on three DOMs that confirm the […]
Last week was relatively quiet at the Pole, offering a good opportunity to get out and reflag the flag line between the IceCube Lab (ICL) and the station. They drill new holes and replace flags as needed to keep the line well maintained. The flags are easy to see now while the sun is still […]
Well, now it’s official—the South Pole station has closed for the winter. Above is a great shot that IceCube winterover Martin captured of the last passenger-carrying plane to depart. Below, the plane is shown being refueled, followed by a view of its take-off as it heads for McMurdo captured from the station’s observation deck. The […]
It’s still light outside, but winter at the South Pole is fast approaching. There were both arrivals and departures last week, and we can see that the departures (above) well outnumbered the arrivals (below). At this point, all the winterovers who will remain on station for this winter have arrived, and team building activities are […]
IceCube collaborator Frank G. Schroeder, assistant professor at the Department of Physics and Astronomy of the University of Delaware and the Bartol Research Institute, has been selected as a 2021 Sloan Research Fellow in Physics as announced today. According to the Alfred P. Sloan Foundation, the Sloan Research Fellowship is one of the most prestigious […]
IceCube collaborator and Harvard physics professor Carlos A. Argüelles Delgado has been selected as a 2021 Sloan Research Fellow in Physics. The Alfred P. Sloan Foundation publicly announced this year’s fellows today. The Sloan Research Fellowships seek to stimulate fundamental research by early-career scientists and scholars of outstanding promise. The two-year fellowships are awarded every […]
