Gamma-ray observations and indirect dark matter searches with the GRAMS project.
GRAMS (Gamma-Ray and AntiMatter Survey) is one of the NASA Physics of the Cosmos suborbital missions, aiming for both MeV gamma-ray observations and antimatter-based indirect dark matter searches. With a low-cost, large-scale LArTPC (Liquid Argon Time Projection Chamber) detector, GRAMS can provide significantly improved sensitivities to gamma rays in a historically under-explored energy regime often referred to as the MeV Gap. GRAMS can also extensively probe a new dark matter parameter space via low-energy antinuclei measurements, including the regions suggested by the Fermi GCE (Galactic Center Excess) and AMS-02 antiproton excess. We recently had a successful engineering balloon flight in Japan and an antiproton beam test at J-PARC to demonstrate our detector performance. We are now preparing for the prototype balloon flight (pGRAMS) from Tucson, Arizona, in early 2026. In this talk, I will present an overview and the current status of the GRAMS project.
The McDonald Institute seminar will be held in Stirling 501. A zoom link is also available and shared via email by the organizers. Please reach out to admin@mcdonaldinstitute.ca for access.
