On the morning of November 24, the sub-forum of the 6th Shan Hai Forum,organized by School of Physics and Astronomy, was held at TIANQIN Research Center on Zhuhai Campus under the theme of “Astronomy and physics in the era of gravitational wave”. Scholars from National Sun Yat-sen University (NSYSU), Xiamen University (XMU) and Sun Yat-sen University (SYSU), gathered together to discuss academic topics and delivered an impressive academic report for students and teachers. The guests present included Guo Zhengyu, assistant professor of NSYSU; Prof. Gu Weimin and Prof. Wang Junfeng from XMU; Prof. Li Miao, Prof. Feng Longlong, Prof. Ye Xianji, Prof. Lin Weipeng and Prof. Huang Zhiqi from SYSU’s School of Physics and Astronomy. Prof. Feng Longlong hosted the forum, which was packed with participants.
Prof. Feng Longlong introduced the development of Shan Hai Forum and the theme of the sub-forum in detail. He also mentioned that Shan Hai Forum acted as a bridge for communication and cooperation among NSYSU, XMU, and SYSU, and promoted a deeper, closer and more extensive cooperation across the straits.
Prof. Li Miao, on behalf of the School of Physics and Astronomy, expressed welcome and gratitude to the distinguished guests present at the forum. He said, “There has been a long history of brotherhood we three universities share together. The School of Physics and Astronomy, as a newly established school, organized the sub-forum of Shan Hai Forum for the first time. We genuinely hope that we can take this opportunity to pave the path for trilateral cooperation in physics and astronomy and contribute to inclusive communication.
Prof. Li Miao introducing the School of Physics and Astronomy
Guo Zhengyu, assistant professor from NSYSU, talked about “Microwave Laser Cosmology Plan: Measurement of Hubble Constant and Quality of the Black Hole”. Prof. Guo said that the plan was designed to observe the accretion disc of water molecules maser around supermassive black hole located in the center of active galaxies and use the orbital characteristics of how water molecules orbit the black hole to measure the black hole mass and the distance of the galaxies. This plan also probed into the possibility of using water molecule maser in active galaxies to detect the fusion of two black holes.
Prof. Ye Xianji elaborated on the TianQin Plan. According to Ye, gravitational wave detection has brought us unprecedented technological challenges. The key technological indicators include: the accuracy of inter-satellite laser ranging reaching 10-12 meters; the acceleration disturbance of detected residual mass reaching 10-15 m/s2. TIANQIN Research Center will rely on technology-oriented experimental programs and implement the plan step by step to stably accomplish these goals.
Prof. Gu Weimin introduced the Department of Astronomy (DA) of XMU and its study on black hole accretion. He pointed out that black hole accretion was an effective mechanism for energy release, which was widely used to explain high-energy astrophysical phenomena such as active galactic nucleus, X-ray binary, ultra-luminous x-ray sources (ULXs), Gamma Ray Burst (GRB) etc. The observed features of Ultra soft X-ray source posed a serious challenge to the classic theory of accretion. Future observation of these planets will further define the accretion model.
Prof. Wang Junfeng introduced the research field of cosmology of DA, XMU, including co-evolution of black hole and galaxies, study and discussion over the “missing baryonic matter”.
Prof. Huang Zhiqi from the School of Physics and Astronomy, SYSU delivered a report titled “Current Situation and Prospect of Cosmic Microwave Background Radiation”. He reviewed the theoretical progress and results of Planck satellite observation, ACT ground-based observation and SPIDER balloon observation in recent years, and mentioned the expected outcome of CMB observation planned at home and abroad. In addition, Prof. Huang also introduced the ongoing projects of the School of Physics and Astronomy and its future projects and hoped that guests would join these cosmology projects.

At the forum, students and teachers asked questions and exchanged opinions with sparking ideas. Universities across the straits set up an alliance to gather key universities, cultivate highly competent talents, and push three cities to enter knowledge-oriented era. Shan Hai Forum is a creation of promoting regional cooperation and enriching education system. It is believed that these three universities will promote further cooperation, accelerate resource integration, strengthen academic communication and cooperation in scientific research and intensify initiative and innovation in order to build an “academic circle across the straits” and cultivate more scientists and technical experts with both professional competence and integrity, thereby making contributions to China’s scientific development.
