Revealing galactic history with cosmic rays

Unlocking the Milky Way’s history through cosmic rays: UMBC nuclear physicist Priyashini Ghosh is leading a first-of-its-kind experiment at the Facility for Rare Isotope Beams (FRIB), measuring how chromium-52 breaks apart as it travels through space. Her work fills critical data gaps, sharpening models of galactic chemical evolution and supporting NASA's upcoming TIGERISS mission.
