The IceCube Collaboration publishes today a new measurement of the all-particle cosmic ray energy spectrum in the energy range from 1.6 PeV to 1.3 EeV using data from IceTop, the surface component of the IceCube Neutrino Observatory. The measured spectrum exhibits clear deviations from power law behavior. These resultshave just been submitted to Physical Review D. […]
The IceCube Collaboration presents the results of a first search for self-annihilating dark matter in nearby galaxies and galaxy clusters. This analysis has been submitted today to Physical Review D. […]
Aya Ishihara recognized at ICRC 2013 by the International Union of Pure and Applied Physics for her discovery of two extremely high-energy neutrinos. […]
With nearly fifty presentations and posters, the IceCube Collaboration will contribute heavily to the International Cosmic Ray Conference (ICRC), which begins today in Rio de Janerio, Brazil. […]
It was the first winter open mic session and IceCube winterover Felipe was behind his drums and cymbals. They really do have everything down there, don’t they? […]
Could they ever tire of viewing auroras at the Pole? Hmm, not sure. But regardless, they do have other things to do besides stare up at the sky. First, there’s work. Then, there are extracurricular activities. … […]
A green sky flecked with swirling patterns of white lines. That’s what you get from sixty 30-second exposures taken through a ceiling dome at the South Pole station and made into a composite image. The IceCube winterovers have been capturing some amazing photos at the South Pole. […]
Antarctica is often described as the coldest, driest, and windiest place on earth. Cold and dry might be hard to discern from photos, but windy? These flags give it away—here, they’re taking a real beating. The group photo below (also with flags flapping away) was orchestrated to commemorate the invention of the Ethernet 40 years ago (they’re posing with a long Ethernet cable held between themselves). The photo garnered a response from the inventor himself, Bob Metcalfe, then at Xerox PARC. […]
A recent measurement of the Moon shadow in TeV cosmic rays with the IceCube telescope sets an upper limit on the detector’s absolute pointing accuracy to 0.2 degrees. The IceCube Collaboration presents these results in a paper submitted today to Physical Review D. […]
