Title: Investigations into the mysteries of Ultra-High Energy Cosmic Rays by the Telescope Array
Speaker: Jihyun Kim, Osaka Metropolitan University
Abstract: Ultra-high energy cosmic rays (UHECRs) are energetic charged particles with E > 10^18 eV that impinge on Earth’s atmosphere from outer space. Their energies are much higher than those that can be achieved in laboratories such as the Large Hadron Collider. 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 into understanding the most violent objects in the universe. The Telescope Array experiment in Delta, Utah, is the largest observatory for UHECRs in the northern hemisphere. In this presentation, I will introduce the experiment, highlight its key findings, and discuss future prospects in the field of UHECRs.
