Project Grant 1506232

The National Science Foundation (NSF) Division of Physics awarded a $500,000 Project Grant under the Mathematical and Physical Sciences program (CFDA 47.049) to the Trustees of the Colorado School of Mines to conduct a study on the highest energy cosmic rays using the Pierre Auger Observatory (PAO). This project will leverage innovative techniques to study the PAO detector and atmospheric systematic uncertainties, enabling a deeper understanding of ultra-high-energy cosmic ray (UHECR) sources...

The National Science Foundation awarded a $249,804 project grant to Michigan Technological University under the Mathematical and Physical Sciences program (CFDA 47.049) to enhance the neutrino sensitivity of the Pierre Auger Observatory in Argentina from September 1, 2021 through August 31, 2024. The grant will support efforts to strengthen the Observatory's ability to detect neutrinos and thereby increase scientific understanding of major problems confronting the nation, as outlined in the...

The National Science Foundation Division of Physics awarded Colorado School Of Mines $230,000 on September 1, 2026, under the Mathematical and Physical Sciences program to conduct in-situ cross-calibration of two cosmic-ray observatories and measure discrepancies in their energy-scale measurements. The project, AUGER@TA, operates an array of water-Cherenkov detectors embedded within the Telescope Array footprint in Utah to directly cross-calibrate the Pierre Auger Observatory and the Telescope...

This Project Grant award from the National Science Foundation (NSF) Directorate for Mathematical and Physical Sciences (CFDA 47.049) provides $285,627 to fund the continued operation of the Askaryan Radio Array (ARA) experiment at the South Pole. ARA is a neutrino astrophysics observatory designed to detect ultra-high energy neutrinos from astrophysical sources. The grant supports ongoing operations and data collection for the five-station ARA detector, as well as development of...

The University of Utah will operate the Telescope Array Observatory through a $865,000 project grant from the National Science Foundation (NSF) Mathematical and Physical Sciences program. Over a three-year period from September 2021 through August 2024, the grant will support operation of the observatory to advance understanding of major problems in astrophysics. Located in Delta, Utah, the Telescope Array Observatory uses a large-aperture optical reflector and scintillation detectors to study...

This Project Grant award, valued at $171,330, was provided by the National Science Foundation (NSF) Directorate for Mathematical and Physical Sciences to the University of Wisconsin System. The grant funds the continued operation and development of the Askaryan Radio Array (ARA) experiment, a cutting-edge neutrino astrophysics observatory located at the South Pole. The key products and services delivered through this award include: Ongoing operation and data collection for the ARA experiment,...

This Project Grant award from the National Science Foundation's (NSF) Mathematical and Physical Sciences (CFDA 47.049) program provides $1,499,710 to the University of Maryland, College Park to support the continued operation of the High-Altitude Water Cherenkov (HAWC) Gamma-Ray Observatory in Mexico. The HAWC observatory is a sensitive wide field-of-view telescope that conducts continuous deep surveys of the very high-energy (VHE) gamma-ray sky, enabling research into the origins of cosmic...

The National Science Foundation Division of Physics awarded the University of Utah $500,000 on September 1, 2026, under the Mathematical and Physical Sciences program (CFDA 47.049) to support base operations of the University of Utah Cosmic Ray Group and analysis of Telescope Array Observatory data. The University of Utah hosts an international collaboration operating the Telescope Array Observatory in Utah, which studies ultrahigh-energy cosmic rays—the highest-energy particles known,...

The National Science Foundation awarded a $574,603 Project Grant under the Mathematical and Physical Sciences program (CFDA 47.049) to researchers at the California Institute of Technology (Caltech) and the Jet Propulsion Laboratory (JPL). The funding supports the development of advanced analysis methods for measuring the energy spectrum and mass composition of ultra-high-energy cosmic rays using the Owens Valley Radio Observatory Long Wavelength Array (OVRO-LWA). Key activities include...
