Research, teaching and public engagement in Physics at UW–Madison
Congratulations to Associate Professor Ke Fang on her promotion with tenure, to Professor Justin Vandenbroucke on his promotion to full professor, and to Profs. Dan Hooper and Britton Plourde who were both granted tenure! Prof. Fang is an experimental particle astrophysicist and WIPAC investigator who studies the origins of subatomic particles and their fundamental nature …
The Milky Way galaxy is an awe-inspiring feature of the night sky, dominating all wavelengths of light and viewable with the naked eye as a hazy band of stars stretching from horizon to horizon. Now, In a June 30 article in the journal Science, the IceCube Collaboration — an international group of more than 350 …
Congrats to Ke Fang, assistant professor of physics, WIPAC faculty member, and HAWC spokesperson, on earning an NSF CAREER award! CAREER awards are NSF’s most prestigious awards in support of early-career faculty who have the potential to serve as academic role models in research and education and to lead advances in the mission of their …
Every second, about 100 trillion neutrinos pass through your body unnoticed. At the South Pole, the IceCube Neutrino Observatory detects these elusive particles and works to identify their astronomical origins to help unlock mysteries of the universe. Such an undertaking requires a massive amount of data, with one terabyte of data recorded daily by IceCube. …
On Earth, billions of subatomic particles called neutrinos pass through us every second, but we never notice because they rarely interact with matter. Because of this, neutrinos can travel straight paths over vast distances unimpeded, carrying information about their cosmic origins. Although most of these aptly named “ghost” particles detected on Earth originate from the …
This story was originally published by WIPAC Back in 2013, the IceCube Neutrino Observatory—a cubic-kilometer neutrino detector embedded in Antarctic ice—announced the first observation of high-energy (above 100 TeV) neutrinos originating from outside our solar system, spawning a new age in astronomy. Four years later, on September 22, 2017, a high-energy neutrino event was detected coincident …
This post was originally published by the IceCube collaboration. Several UW–Madison physicists are part of the collaboration and are featured in this story A month ago, the Seattle Community Summer Study Workshop—July 17-26, 2022, at the University of Washington—brought together over a thousand scientists in one of the final steps of the Particle Physics Community Planning …
Gravitational waves (GWs) are a signature for some of the most energetic phenomena in the universe, which cause ripples in space-time that travel at the speed of light. These events, spurred by massive accelerating objects, act as cosmic messengers that carry with them clues to their origins. They are also probable sources for highly energetic …
Astronomers have long sought the launch sites for some of the highest energy protons in our galaxy. Now, a study using 12 years of data from NASA’s Fermi Gamma-ray Space Telescope (Fermi) confirms that a remnant of a supernova, or star explosion, is just such a place, solving a decade-long cosmic mystery. Previously, Fermi has shown that the …
This story was originally published by IceCube. The IceCube Neutrino Observatory, a massive astroparticle physics experiment located at the South Pole, will be featured in two upcoming documentaries about neutrinos produced for the BBC and PBS NOVA. Sometimes called the world’s biggest and strangest telescope, IceCube comprises over 5,000 light sensors deployed in a cubic …
