The Vieregg Lab

We study cosmology and neutrino astrophysics utilizing radio and millimeter wavelength detection techniques.

Radio Detection of Ultra-high Energy Neutrinos: We are leaders in the design, development, simulation, and analysis of data from experiments that look for ultra-high energy astrophysical and cosmogenic neutrinos through the radio emission that is made as a result of neutrino interactions on Earth. We contribute to major efforts in this field, including BEACON, RNO-G, and PUEO.

Precision Measurements of CMB Polarization: We build telescopes that make precision measurements of the polarization of the CMB to learn about an inflationary period in the early universe and about the properties of neutrinos, among other things. We are involved in the development of CMB-S4, a large-scale ground-based CMB experiment.

Ongoing Projects


We are the lead institution on the PUEO experiment, a NASA long-duration balloon (LDB) experiment and a part of the NASA Pioneers program. Currently in construction, PUEO will aim to detect radio signals generated via the Askaryan effect from the highest energy neutrinos interacting in the Antarctic ice sheet. PUEO will be sensitive to higher energy neutrinos than other techniques. PUEO is scheduled to launch from McMurdo Station in Antarctica in December of 2025.

We are co-leading the development and deployment of RNO-G, an in-ice radio detector that is being deployed to Summit Station in Greenland. RNO-G builds on the success of ARA and incorporates new interferometric phased array trigger technology. RNO-G will have the sensitivity required to observe ultra-high energy neutrinos. Construction is in progress, with seven out of 35 total science stations completed.

BEACON is a mountainside radio detector concept that aims to detect radio emission from air showers created by tau leptons that result from the interaction of tau neutrinos in the Earth. We have helped design and develop an initial prototype system, which is located at Barcroft Station of the White Mountain Research Station in California. Our lab is also involved in hardware development for future stations, and we have worked on searches for cosmic rays using the prototype.

We are part of the CMB-S4 collaboration, a next-generation ground-based experiment studying the cosmic microwave background. The instrument, located at the South Pole and in Chile, will be made up a suite of small and large aperture telescopes, housing 500,000 detectors. In particular, we are interested in constraining inflation and properties of neutrinos by measuring the B-mode polarization signature.
