Prof. Tongjie Zhang

Beijing Normal University, China

Biography:

Tongjie Zhang is a professor and doctoral supervisor of Beijing Normal University. Member of China Astronomical Society ; member of International Astronomical Union (IAU) Cosmology Branch; chinese member of the International Astronautical Congress (IAC) Standing Committee on Extraterrestrial Civilization Program (IAA SETI). The main research directions are physical cosmology, cosmology theory and observation, and extraterrestrial civilization theory and observation. In international astrophysics and physics journals such as ApJ, MNRAS and PRD, more than 100 SCI articles (including PRL and Nature Astronomy) have been cited for nearly 1500 times, with a maximum of 400 citations per article. He led the research team to propose a new method to directly measure the expansion acceleration of the universe by using the 21 cm absorption line generated by radio radiation passing through the intergalactic neutral hydrogen cloud. By using the ' Tianhe-2 ' supercomputer, the numerical simulation of cosmic neutrinos and dark matter is carried out, showing the long evolution process of the universe for about 13.7 billion years.
