Ongoing Research


The Greenland Neutrino Observatory is a next-generation radio detector for ultra-high energy neutrinos. The first detectors are set to deploy at Summit Station Greenland in Summer 2015, and we are leading the development effort.

BICEP3 is an experiment that will observe the microwave sky on degree angular scales to make precision measurements of the polarization of the Cosmic Microwave Background. BICEP3 will follow up on the detection of B-mode polarization by BICEP2, looking for the pattern imprinted on the CMB by gravitational waves created during Inflation. It is set to observe beginning in the Winter of 2015 at the South Pole.

Recent News! After a successful integration and installation at South Pole, BICEP3 first light was on January 18, 2015.

The Keck Array

The Keck Array is an array of five polarimeters of similar design to BICEP2. It has the same science goals as the BICEP series of instruments, but with a factor of five increase in the number of detectors compared to BICEP2, leading to increased sensitivity. The Keck Array observes at 100 GHz and 150 GHz, and will soon add 220 GHz channels.

Recent News! We just completed the successful installation of two 220 GHz receivers in January 2015. They will begin observation in February.

The ANITA experiment is a NASA long-duration balloon experiment that detects the radio signals generated via the Askaryan effect from ultra-high energy neutrinos interacting in the Antarctic ice sheet. The third flight of ANITA will fly in December 2014 in Antarctica, with world-leading sensitivity to the highest energy neutrinos.

Recent News! The third flight of ANITA launched on December 18, 2014 and flew for 22 days.
