| Abstract: | The GRAPES-3 experiment located in Ooty, Tamil Nadu recently discovered a hardening in the cosmic ray proton spectrum above 165 TeV which disfavours single power law description of the spectrum up to the Knee energy (~3 PeV). The measurements were performed over an energy range of 50 TeV to 1.3 PeV using the data collected with a high density array of plastic scintillators and a large area muon telescope, bridging the gap between space-based and ground-based measurements. Furthermore, two significant small-scale anisotropic structures in the cosmic ray arrival distribution were detected at a median energy of 16 TeV, consistent with results from the HAWC and ARGO-YBJ experiments. Both these results could enhance our understanding of cosmic ray sources and acceleration mechanisms. This presentation will highlight these findings, along with updates on the status of the detector upgrade and future plans. |
