Seminar: (I) The LHAASO experiment: Overview and highlights (II) LHAASO results on the Sun, supernova remnant and dark matter

ABSTRACT

The Large High Altitude Air Shower Observatory (LHAASO) is a major national science and technology infrastructure facility. It is located on Haizi Mountain in Daocheng, Sichuan Province, South-west of China, at an altitude of 4410 meters above sea level. Since its completion in July 2021, LHAASO has achieved internationally leading levels in ultra-high-energy gamma-ray detection sensitivity, very-high-energy gamma-ray survey sensitivity, and the energy coverage range of cosmic rays. This marks a groundbreaking advancement for China in the fields of cosmic ray research and high-energy gamma-ray astronomy. Leveraging data from LHAASO, significant breakthroughs have been made in addressing the century-old mystery of the origin of Galactic cosmic rays, advancing high-energy gamma-ray astronomy, exploring cosmic-ray-related physics, and probing new physics frontiers. The upcoming talks will introduce the LHAASO experiment, its remarkable scientific achievements, and its profound impact on international particle astrophysics research, as well as its future development prospects.

BIOGRAPHY

Songzhan Chen (陈松战) is a  scientist researcher at the Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences. He earned his bachelor's degree from Henan Normal University in 2004 and obtained his Ph.D. from IHEP in 2009. Since 2021, he has served as the Chair of the Physics Coordinator of LHAASO Collaboration. Based on LHAASO data, he has made significant contributions to high-energy gamma-ray astronomy. In 2023, He was awarded the CAS Outstanding Science and Technology Achievement Prize as a key contributor to the LHAASO research collective.

Zhe Li(李哲) is a scientist researcher at IHEP. She earned her Ph.D. from Chengdu University of Technology in 2013 and subsequently completed two years of post-doctoral research in IHEP. Since then, she works at LHAASO and focus on the observation and studies of the Sun, suppernova remnant and dark matter.
