[Seminar] Dr. Jihyun Kim (University of Utah), November 22nd, 2022.

We are delighted to announce that we will have an Astroparticle Physics Seminar given by Dr. Jihyun Kim from the University of Utah on November 22nd. Please join and welcome her talk together.

This seminar will be in-person. Please get in touch with Prof. Rott to get detailed information beforehand to join this seminar.


Title: Ultra-High Energy Cosmic Rays Observed by the Telescope Array Experiment

Speaker: Dr. Jihyun Kim (University of Utah – Department of Physics and Astronomy, High Energy Astrophysics Institute)

Date & Time: Tuesday, November 22nd, 2022. 16:30 KST (8:30 CET / 0:30 MST)

Place: Creative Learning Room, 7th Floor, Samsung Library

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.
