13 Months Below Zero

The IceCube Neutrino Observatory at the South Pole indirectly observes the action of neutrinos, subatomic particles so small they pass through most matter undetected, via a large array of optical modules frozen deep in the ice. UW-Madison is the lead institution in charge of data-gathering and maintenance — that means someone needs to be at the South Pole all winter. The team in 2022-2023 was Hrvoje Dujmovic and Marc Jacquart, and they will talk about the experience, followed by a screening of the film Chasing the Ghost Particle, at this free event.
