Hans Niederhausen, IceCube collaborator and postdoctoral research associate at Michigan State University (MSU), has been selected as the recipient of the 2023 Shakti P. Duggal Award presented by the International Union of Pure and Applied Physics (IUPAP). Niederhausen was acknowledged for “his development and application of advanced analysis methods in neutrino astronomy.” The Duggal Award […]
IceCube collaborator Lu Lu received a 2023 International Union of Pure and Applied Physics (IUPAP) Early Career Scientist Prize “for her contributions to the development of high energy neutrino astronomy in the PeV energy region.” Lu accepted the award on July 27 during the opening ceremony at the 38th International Cosmic Ray Conference (ICRC) held […]
Introduction This data release accompanies results presented at ICRC 2023 describing a revisited analysis of the HESE (high-energy starting events) sample with an additional 4.5 years of data that employs a full-resimulation reconstruction approach, DirectFit, which exactly incorporates recent updates in glacial ice modeling. For further details refer to the IceCube publication: “Updated Directions of […]
The sources of cosmic rays—extremely energetic particles that rain down on Earth—have been a long-standing mystery in the field of astronomy. Cosmic-ray accelerators in the PeV energy range, known as PeVatrons, produce pions when the cosmic rays interact with their surroundings. These pions then decay into gamma rays and nearly massless particles called neutrinos. These […]
Christmas in July continued last week with all sorts of activities, ranging from a pool tournament to a pie-eating contest. And for those who enjoy competitive eating, they weren’t limited to just pies—a “donuts on a string” eating contest was also part of the festivities. In addition, the station held a Christmas trivia night and […]
A barren landscape, the South Pole is actually a desert. It’s not the kind of desert most people imagine, with lots of sand and heat and maybe a camel ambling by. Instead of sand, there’s snow. But almost all of that snow has blown in from more coastal regions of the continent, ushered in from […]
We are pleased to announce the following PhD graduates who successfully defended their thesis in the spring of 2023: Stefan Countryman Pranav Dave Martin Antonio Unland Elorietta Sreetama Goswami Minjin Jeong Cristian Jesus Lozano Mariscal Sourav Sarkar Steve Sclafani Manuel Silva […]
Not everyone celebrates Christmas in July, but they do at the South Pole station, where traditions prevail. Last week started off the festivities with the appearance of a tree and presents in the galley. More activities and decorations are planned for upcoming weeks. The weather was nice and cold as a fitting complement to the […]
Our Milky Way galaxy is an awe-inspiring feature of the night sky, viewable with the naked eye as a horizon-to-horizon hazy band of stars. Now, for the first time, the IceCube Neutrino Observatory has produced an image of the Milky Way using neutrinos—tiny, ghostlike astronomical messengers. In an article to be published tomorrow, June 30, […]
For the first time, an international team of scientists presents evidence of high-energy neutrino emission from the Milky Way. The results were published on June 30, 2023 in Science (link). See the press release here. […]
