What Are They Doing?

Photo by Rishabh Khandelwal. IceCube is located at the South Pole and records the interactions of a nearly massless sub-atomic messenger particle called the neutrino. IceCube searches for neutrinos from the most violent astrophysical sources: events like exploding stars, gamma ray bursts, and cataclysmic phenomena involving black holes and neutron stars. The IceCube Neutrino Observatory is a powerful tool to search for dark matter, and could reveal the new physical processes associated with the enigmatic origin of the highest energy particles in nature. In addition, IceCube studies the neutrinos themselves using the 100,000 neutrinos detected per year produced by cosmic rays in the atmosphere. Their energies far exceed those from accelerator beams. IceCube encompasses a cubic kilometer of instrumented ice, and is the largest detector by volume ever built.

The fully built ARA project, also located at the South Pole, will have an effective volume 100 times bigger than IceCube. The trade off is that it is only capable of observing radio waves from extremely high energy neutrinos, a million times more energetic than the neutrinos produced by cosmic rays in the atmosphere. This neutrinos are extremely rare, which is why such a large detector is needed to increase the chance of seeing one.

Where Are They?

The IceCube site is about one kilometer from the South Pole station, which supplies the necessary logistics of food, power, and shelter. Despite the cold outside, life inside the station is relatively luxurious with comfortable beds, cooked meals, and showers twice a week. The South Pole is reached by plane from McMurdo Station on the coast of Antarctica, accessible from the end of October through mid-February, after which time temperatures become too low for planes to operate safely. About 40 people remain at the South Pole station the rest of the year, which is known as wintering over. IceCube has two people dedicated to overseeing the operation of the telescope during this period at the South Pole.

Meet the Team

Eric Muhs's picture
United States

Eric Muhs taught physics & astronomy in public schools for 32 years, most recently at Ballard High School in Seattle. He was AAPT’s “Washington State Physics Teacher of the Year” in 2013. With students, he built a robot that flew aboard NASA’s “vomit comet” zero-gravity airplane, a cosmic-ray detector that flew to the edge of space on a NASA high-altitude balloon, and an experiment that left the Earth on one of the last Space Shuttle flights. Mr. Muhs left Ballard High School in June to pursue other interests in education, including informal education opportunities, and spent the summer teaching Upward Bound, and building a solar-powered trailer that can be rented for off-grid events and sustainability education. He is thrilled to be working with the IceCube team.

Dr. Madsen is the chair of the Physics Department at UW-River Falls and Associate Director of the IceCube Neutrino Observatory where he directs the education and outreach program. His research interests include heliophysics and astrophysics, which he has studied at his various projects in Antarctica. In addition to research, Dr. Madsen is committed to reaching a broad audience beyond the research community. He is involved in education and outreach for the IceCube project including professional development courses for teachers and science and math instruction for the UWRF Upward Bound Program. He collaborates with a number of programs and institutions in addition to PolarTREC, including the Knowles Science Teaching Foundation, UW-River Falls Upward Bound and McNair Programs, and service groups (Rotary International, Boy and Girl Scouts, university alumni associations, etc.). You can read more about Dr. Madsen's work here and here.

"Working in Antarctica is a wonderful adventure, and it is great to provide opportunities for others to have this awesome experience."

Michael DuVernois is a Senior Scientist with the Wisconsin IceCube Particle Astrophysics Center and a Research Professor with the Department of Physics at the University of Wisconsin in Madison. He is an experimental physicist working on the IceCube and ARA neutrino observatories at the South Pole. His other research interests include high-energy gamma-ray astronomy, humanitarian demining, and detector development for particle and astro-particle physics. Less technically, he has bowled on all seven continents, and is found most Austral Summers at the South Pole supervising students and technicians. He has previously flown satellite experiments in orbit and through the solar system, balloon instruments to the top of the Earth’s atmosphere, and built instrumentation for mountain-top and extended ground-based observatories.
