Results from the Telescope Array Experiment

Understand

The Telescope Array (TA) is the largest experiment in the northern hemisphere studying ultrahigh energy cosmic rays.

• TA is a hybrid experiment, which means it has two detector systems: a surface detector and a fluorescence detector.
• In this paper we report on results from TA on the spectrum, composition, and anisotropy of cosmic rays.
• The spectrum measured by the TA surface detector, cosmic ray composition measured with the TA fluorescence detectors operating in stereoscopic mode, and a search for correlations between the pointing directions of cosmic rays, seen by the surface detector, and AGN's are presented.
