Energy Physics from May 10th to June 1st.

On May 12th, Prof. Sunyaev delivered a lecture entitled The scientific goals of Spectrum-X/eRosita X-Ray observatory (Russia, Germany)-all sky survey, 100 000 clusters of galaxies and 3 Mln AGNs, cosmology and astrophysics, which reviewed the scientific objectives of the eRosita X-ray telescope on the Russian SRG satellite. Prof. Sunyaev then discussed the possible future cooperation of the HXMT and eRosita projects with IHEP researchers and postgraduates. On May 13th, Prof. Sunyaev delivered a second public talk at IHEP entitled Disk accretion onto neutron stars with weak magnetic fields: theory of the radiation dominated boundary layer.

During his visit, Professor Sunyaev spoke highly of IHEP’s fundamental research, experiments and technology R&D. He hopes to strengthen bilateral exchanges and visits, and enhance mutual understanding and cooperation through complementary research, leading to the further development of particle astrophysics. Prof. Sunyaev’s visit was part of the CAS Einstein Professorship Program.

About Prof. Rashid A. Sunyaev

Prof. Sunyaev was educated at the Moscow Institute of Physics and Technology (MIPT) and Moscow University, becoming a professor at MIPT in 1974. He was the head of the High Energy Astrophysics Department of the Russian Academy of Sciences from 1982 to 2002, and has been chief scientist of the Academy's Space Research Institute since 1992. He has also been a director of the Max Planck Institute for Astrophysics in Garching, Germany since 1996.

In the 1970s, he and his teacher Yakov B. Zel'dovich developed a theory for the evolution of density fluctuations in the early universe. With Nikolay I. Shakura, he developed a model of accretion onto black holes from a disk, and he has proposed a signature for X-radiation from matter spiraling into a black hole.

About the Einstein Professorship Program

The Einstein Professorship Program was initiated by the CAS in 2004. Einstein Professorships are awarded each year to 20 distinguished international scientists actively working in the frontiers of science and technology, for conducting lecture tours in China. The program aims to strengthen science and technology links, cooperation and exchange between CAS scientists and the respective Einstein Professors and their laboratories, thus enhancing the training of future generations of scientists in China.
