More on astrophysical neutrinos yet no track of charmed mesons

The IceCube Collaboration has expanded the search for neutrino interactions in IceCube, lowering the range of deposited energy down to 1 TeV. The goal was a better understanding of the different contributions to the neutrino flux in IceCube and hopefully to measure the charmed-meson component for the first time. The results of this study have been submitted today to Physical Review D. […]

Week 36 at the Pole

As dawn approaches, the sky is cast in a glow that reflects off the sides of the South Pole station. Inside the station, they’ve begun to remove the window covers that remain in place all winter, there to minimize light pollution for sensitive experiments at the Pole. […]
