The 12th Tsung-Dao Lee Frontier Lecture: The first results of LHAASO: Opening The UHE Gamma-ray Astronomy
by
Room 300, NO.5, Science Building
The Large High Altitude Air Shower Observatory (LHAASO) as the largest ground based Gamma Ray detector array has the 1/2 array operated for months. Many VHE gamma ray sources has been observed including well known sources such as J1809+06 and Mkr421. With many sources found having strong emission of gamma rays in UHE(> 0.1 PeV) band, LHAASO is opened a completely new window of gamma ray astronomy with its unprecedented sensitivity at energies above 10 TeV and extremely high background rejection capability. It has detected super-PeV gamma-like events, including the record high energy of 1.4 PeV in history. With also measured SEDs of several galactic gamma sources above 100 TeV, LHAASO reveals that our galaxy is full of PeVatrons. This enables an exploring for hadronic PeVatrons which are the origin of the cosmic rays, particularly with the operation of the full scale LHAASO array. The experiment status will be updated.
PS：the lecture will be given in Chinese
Zhen Cao, was awarded the Ph. Doctoral degree at the Institute of High Energy Physics(IHEP), Beijing, in 1994.He worked for the Physics Department of University of Oregon as a Research Associate since 1994 and moved to the Physics Department of University of Utah also as a research associate in 1998, then was promoted as a research associate professor since 2003 until he left the position in 2009.In 2004, he was selected as an “outstanding Scientist abroad (as known as “Hundred Talents”)” by Chinese Academy of Science (CAS) and was employed as a professor in the Particle Astrophysics Research Center of IHEP and was qualified to be an advisor of Ph. Doctoral students. Since 2012, he has been the deputy director of the Particle Astrophysics Key Laboratory of CAS. Since 2013, he has been appointed to be the Chief Scientist and director of the project Large High Altitude Air Shower Observatory (LHAASO), one of mega projects for the major national infrastructure building. He was employed as a professor of University of CAS since 2015. He has been elected as the director of “Tianfu Cosmic Ray Research Center” of IHEP since 2019. He devoted himself in cosmic ray physics and gamma ray astronomy since 1994, and has been very active throughout his research career. He participated a couple of major cosmic ray experiments in the world. He has been leading a couple of experiments and playing a central role in proposing and implementation of the experiments. He has established significant achievements in the field with more than 120 scientific articles published in the major journals around the world. The citation of those articles counts over 5,500 in total. He was elected to be the standing board member and the deputy secretary general of the High Energy Physics Society of Chinese Physics Society since 2007. Currently, he has been the members of Astroparticle Physics Commission (C4) of International Union of Pure and Applying Physics (IUPAP) and of Astroparticle Physics International Committee (WG10) of IUPAP since 2014.
