GRAPES-3 experiment unveils unexpected twist in cosmic ray spectrum

Mumbai, India (SPX) Feb 05, 2024

The Tata Institute of Fundamental Research's GRAPES-3 experiment, based in Ooty, India, has made a pivotal discovery in the field of cosmic ray physics. Researchers have identified a new characteristic in the cosmic-ray proton spectrum at an energy level of around 166 tera-electron-volt (TeV), a finding that spans a measurement range from 50 TeV to just over one peta-electron-volt (PeV).
