Prof. Yizhong Fan gave a colloquium in School of Physics and Technology

Invited by School of Physics and Technology, Prof. Yizhong Fan gave a colloquium titled “Gravitational Wave Astronomy and Astrophysics” on November 18 in the conference room 436 of Xingjian Building.

Professor Yizhong Fan first started from Newton's theory and Einstein's general theory of relativity, deriving gravitational waves through the essence of gravity, and introduced the differences between gravitational waves and electromagnetic waves in three aspects: generation, propagation and frequency. Then he described the theoretical generation of high-frequency gravitational wave radiation sources, and introduces the working principle of the LIGO detector to detect gravitational signals. Subsequently, he discussed some major breakthroughs that gravitational waves may make in the detection of compact celestial bodies in the near future. After that, Professor Fan introduced gravitational wave cosmology, using gravitational waves to study dark energy and accurately determine the Hubble constant, and introduced some experimental evidence for the test of gravitational theory. Professor Fan also introduced some of their work on the equation of state of neutron stars and the origin of superiron elements.

Prof. Yizhong Fan received a bachelor of science degree from Chang'an University in 2000.7, a master of science degree from Nanjing University in 2003.3, and a doctorate degree of science from Zijin Mountain Observatory in 2006.3. Prof. Yizhong Fan was engaged in high-energy astrophysics research in Israel, Denmark and the United States from November 2005 to March 2010. In April 2010, he was hired as a researcher of the Chinese Academy of Sciences' Hundred Talents Program and started research on indirect dark matter detection. Prof. Yizhong Fan has made important achievements in the indirect detection of dark matter, high-energy astrophysics, and gravitational wave astronomy research. Prof. Yizhong Fan won the 2004 Chinese Academy of Sciences Dean Award (Special Award), 2009 National Outstanding Doctoral Thesis, 2015 National Outstanding Youth Science Fund, 2017 Chinese Academy of Sciences Young Scientist Award, 2018 Jiangsu Province May 1st Labor Medal. He is currently the deputy chief designer of the ground science application system of the dark matter particle detection satellite (also known as the "Wukong"), leading the satellite's scientific team; selected as a young and middle-aged leader in the 2019 "Ten Thousand Talents Program".
