Story Highlights

The IceCube Neutrino Observatory is the first detector of its kind, designed to observe the cosmos from deep within the South Pole ice.

As neutrinos pass through the Earth, some interact with protons or neutrons, producing photons which then travel through the ice, and can be detected by a sensor.

The sensors transform these signals from neutrino interactions into digital data that is then analyzed to determine whether they represent a local source (Earth's atmosphere) or a distant one.

In March 2021, IceCube announced the discovery of the resonant formation of a W− boson during the interaction of a high-energy electron antineutrino with an electron.

The discovery suggests the presence of electron antineutrinos in the astrophysical flux, while also providing further validation of the standard model of particle physics.

TACC's Frontera supercomputers was among the resources used to detect and confirm the discovery. As one of the most powerful high-performance resources available to IceCube researchers, it also enabled previous computational analyses that made the discovery possible.
