VERMILLION, S.D. – Instead of turning their attention to the sky during Astronomy Day, University of South Dakota students and Vermillion community members will focus on what’s deep below the surface of the Earth as they hear first-hand about the progress being made to do astronomy at the world’s largest neutrino detector.
Francis Halzen, Ph.D., a theoretician from the University of Wisconsin–Madison studying particle physics and astrophysics, will speak on USD’s campus in Farber Hall Monday evening, April 9, at 6:30 p.m. about his experience as the principal investigator at the IceCube Neutrino Observatory.
The observatory, which is located at the South Pole, utilizes 86 holes over 1.5 miles deep melted into the Antarctic icecap to search for neutrinos from the most violent astrophysical sources, including events such as exploding stars, gamma-ray bursts, and cataclysmic phenomena involving black holes and neutron stars.
The Astronomy Day presentation by Halzen titled “Ice Fishing for Neutrinos” will focus on the research conducted at IceCube which recently revealed a flux of neutrinos reaching the earth from deep in the cosmos, with energies more than a million times greater than those humans can produce in accelerators.
