Research Overview

Studying very high-energy gamma rays and cosmic rays from the Universe and Earth.

Research Subjects

  • 1. Searching for ultra-high-energy gamma-ray sources, anti-matter, dark matter from the Universe, and high-energy radiation from thunderclouds.
  • 2. Research and development of radiation detectors.


Astroparticle physicists strive to find the answers to some of the most exciting questions about the Universe. What is the origin of cosmic rays? Where does the acceleration of ultra-high- energy cosmic rays originate? What is the role of violent astrophysical processes? Can we detect dark matter?
The laboratory’s main study is gamma-ray astrophysics, extending from mega-electronvolts (MeV) to peta-electronvolts (PeV), and covers a wide range of phenomena in particle physics and astrophysics, providing one of the most active fields of modern astroparticle physics. Moreover, the laboratory tackles challenges in technology and computing. The Tibet Experiment which is a collaboration between China and Japan, aims to observe cosmic rays and gamma rays with energies greater than 1013 eV at Yangbajing (4.300m above sea level) in Tibet, China.
