○ Abstract: Ultra-high energy cosmic rays (UHECRs) are energetic charged particles with E > 1018 eV that impinge on Earth’s atmosphere from outer space. Their energies are much higher than those scientists can accelerate in the lab. By exploring the nature and origin of UHECRs, we hope to better understand where they are coming from and how they achieve such high energy, thereby giving us a window to understanding the universe. The Cosmic Ray Physics Group at the University of Utah hosts the Telescope Array (TA) experiment in Delta, Utah, which is the largest observatory for UHECRs in the northern hemisphere. In this presentation, I will introduce the experiment and the findings of the TA. I will mainly focus on anisotropies in arrival direction distributions of UHECRs, which is critical to narrowing down source candidates.
