Description

The Telescope Array (TA) experiment is located in the western desert of Utah, USA and observes ultra high energy cosmic rays in the northern hemisphere. In the highest part of the energy region, the cosmic ray energy spectrum shape carries information of the source density distribution. We search for directional differences in the energy spectrum shape. In this study, observed cosmic ray energy distributions are compared between sky areas that contain nearby objects, such as the super-galactic plane, and others that do not.
