The sun has finally gone below the horizon at the Pole, not to peek back up again for another six months or so. IceCube’s winterovers spent some time early in the week finishing up outdoor work in the fading light. Although the weather was rather bad last week, there were a few nice hours of […]
IceCube places constraints on neutrino emission from the brightest gamma-ray burst
On October 9th, 2022, an unusually bright pulse of high-energy radiation whizzed past Earth, captivating astronomers around the world. The luminous emission came from a gamma-ray burst (GRB), one of the most powerful classes of explosions in the universe. Named GRB 221009A, it triggered detectors at NASA’s Gamma-ray Burst Monitor and Large Area Telescope (both on […]
PhD theses granted – Winter 2023
We are pleased to announce the following PhD graduates who successfully defended their thesis in the winter of 2023: Jannes Brostean-Kaiser Raffaela Busse […]
Week 11 at the Pole
Where is the horizon? Well, it must be there somewhere, hidden between the white of the snow on the ground and the white of the cloudy sky above. These winterovers were posing at the ceremonial Pole during a recent “sunset stroll,” which was technically a 3K race but one that could be done in a […]
IceCube meets in Aachen for its spring 2023 collaboration meeting
The spring IceCube Collaboration meeting wrapped up last week in Aachen, Germany, which was hosted by RWTH Aachen University. Over 200 members of the IceCube community attended the meeting either in person or virtually. For the second straight year since the pandemic began, the biannual collaboration meeting was held in person, with virtual offerings for […]
2023 IceCube Impact Awards announced
The results of the tenth edition of the IceCube Impact Awards were announced this week at IceCube’s spring collaboration meeting in Aachen, Germany. During the ceremony, IceCube spokesperson Ignacio Taboada gave each recipient a certificate and mug to commemorate their achievements while those who could not attend joined virtually. The awardees are Cristina Lagunas Gualda […]
Week 10 at the Pole
IceCube winterover Marc stationed himself nicely to get this photo of the sun setting behind the ceremonial South Pole. He photographed it from a distance last month, under clear skies when the sun was still high. But you don’t need a month for the environment to look different. The two photos below of the IceCube […]
IceCube’s first study on seasonal variations of atmospheric neutrinos
Atmospheric muons and neutrinos are the most abundant signals detected in IceCube. They are produced in cosmic-ray-induced air showers in the Earth’s atmosphere. Cosmic rays are high-energy protons and heavier nuclei traveling through space. When these cosmic rays reach Earth and collide with atoms in the atmosphere, they create an avalanche-like cascade of secondary particles […]
Help IceCube decode signals from outer space
Every second, about 100 trillion neutrinos pass through your body unnoticed. At the South Pole, the IceCube Neutrino Observatory detects these elusive particles and works to identify their astronomical origins to help unlock mysteries of the universe. Such an undertaking requires a massive amount of data, with one terabyte of data recorded daily by IceCube. […]
Week 9 at the Pole
Although it was generally quiet last week, IceCube’s winterovers took some interesting photos of their activities and surroundings. First up, weather balloon launching. Winterover Marc put his training to work as he was on weather balloon duty last week. On one of those days, a sundog appeared just at the right time to serve as […]
