Core offering

WIPAC operates the IceCube Neutrino Observatory, a cubic-kilometer particle detector at the South Pole, and several other astrophysics experiments (ARA, HAWC, CTAO, RNO-G, SWGO). It operates scientific infrastructure, conducts research in neutrino astrophysics and high-energy particle physics, and provides data access, computing resources, and collaboration opportunities to international research institutions.

Product overview

WIPAC operates a portfolio of neutrino and cosmic ray detector systems and related scientific infrastructure. The core product is the IceCube Neutrino Observatory, a cubic-kilometer particle detector at the South Pole. Supporting products include the ARA radio array (also at the South Pole), HAWC gamma-ray observatory in Mexico, and CTAO in development. RNO-G and SWGO represent next-generation extensions. WIPAC also offers DECO, a citizen science smartphone app, and Project Hercules educational video game. The theoretical astrophysics program provides research integration across all detectors.

• SWGO (Southern Wide-field Gamma-ray Observatory) Planned ground-based gamma-ray detector in the Southern Hemisphere, designed for wide field of view and nearly 100% duty cycle. To be located in Atacama Astronomical Park in Chile at 4,770 meters altitude, covering energies from hundreds of GeV to PeV scale.
• Theoretical Astrophysics Research Theoretical research program encompassing high-energy neutrinos, cosmic rays, gamma rays, dark matter, black holes, and extreme astrophysical environments. Includes model development and interpretation of data from IceCube, HAWC, and future observatories.
• DECO (Distributed Electronic Cosmic-Ray Observatory) A citizen science project that allows users worldwide to detect cosmic rays and other energetic particles using their cell phones and tablets. Available on Android with iOS version in testing, with global data collection and educational resources.
• Project Hercules An educational video game that enables players to explore the universe through astrophysics concepts, part of WIPAC's outreach and education initiatives.
