Recent Results from Telescope Array

Understand

The Telescope Array (TA) is an experiment to observe Ultra-High Energy Cosmic Rays (UHECRs).

• TA's recent results, the energy spectrum and anisotropy based on the 6-year surface array data, and the primary composition obtained from the shower maximum Xmax are reported.
• The spectrum demonstrates a clear dip and cutoff.
• The shape of the spectrum is well described by the energy loss of extra-galactic protons interacting with the cosmic microwave background (CMB).
