Week 48 at the Pole

Bad weather and low visibility gave a misty, floating appearance to the IceCube Lab (ICL) last week—view of its staircase above and the whole lab below. IceCube’s new winterovers spent some time at the ICL upgrading servers as well as offering tours to South Pole station personnel. A flight brought some new people to the […]

Week 47 at the Pole

And then there were two. Last week at the Pole, IceCube’s previous winterovers, Celas and Moreno (shown above), left the ice for warmer climes. Newcomers Hrvoje and Marc continued settling into their new lives at the station. The detector remained quiet for them this week, giving them more opportunity to tackle some special projects on […]

Exploring the LHAASO ultra-high-energy gamma-ray sources for neutrinos

The origin of high-energy cosmic rays remains a long-standing mystery in particle astrophysics. However, it is thought that they are accelerated by galactic sources called PeVatrons, capable of accelerating particles to energies greater than 1 PeV. Some candidate galactic PeVatrons include pulsar wind nebulae (PWNe)—a type of nebula generated by strong winds of charged particles […]

Week 46 at the Pole

Finally, the annual changing of the guard for IceCube winterovers took place last week at the Pole. Newcomers Hrvoje Dujmovic and Marc Jacquart arrived in time to get in a little training with outgoing winterovers Celas Marie-Sainte and Moreno Baricevic—all four in the photo above. Hrvoje and Marc, who will be at the Pole for […]

Week 45 at the Pole

There was an abundance of color out on the ice last week at the Pole—lots of photo shoots in preparation of celebrating Polar Pride Day on November 18. Above we see some of the winterovers captured in midair as they engaged in a pride “jump.” The photo was taken by South Pole Telescope winterover Aman […]

Week 44 at the Pole

Last week at the Pole there was some more flight activity, bringing in 14 summer crew members but also taking away seven winterovers, seen above walking out to their awaiting plane. IceCube’s new winterovers were not among the arrivals this week, but they’re on their way. During this time of transition, station personnel held an […]

Machine learning method improves reconstruction and classification of low-energy IceCube events

Machine learning (ML) has proven to be an invaluable tool for data analysis, including the field of particle physics. Now, ML techniques are being employed to analyze data collected by the IceCube Neutrino Observatory, a cubic-kilometer array of optical sensors buried in Antarctic ice that detect neutrinos, ghostly subatomic particles that act as cosmic messengers. […]
