Recently, the 2024 Academic Annual Meeting of Gravitation and Relativistic Astrophysics, Chinese Physical Society and the 6th Galileo——Xu Guangqi International Conference were held in Hengyang, Hunan Province. The conference was hosted by the Gravitation and Relativistic Astrophysics of the Chinese Physical Society and International Center for Relativistic Astrophysics, organized by University of South China, and co- organized by Hunan Normal University, Lanzhou University, Institute of Theoretical Physics of the Chinese Academy of Sciences, Hunan University of Arts and Sciences, Zijinshan Observatory of the Chinese Academy of Sciences, and other units. More than 660 experts, scholars, postdoctoral fellows, and graduate students from around the world attended the conference. The conference had in-depth exchanges on the latest research trends and scientific frontiers of gravity and relativistic astrophysics, and the attending scholars shared the latest research results and scientific discoveries.
This conference has set up one main venue and seven sub-venues, and a total of 23 special invited speeches and 287 sub-venue presentations were held. The conference selected 7 outstanding graduate report awards out of 139 student reports. Under the guidance of Professor Zhang Xin, Jin Shangjie, a PhD student in the college of Physics at our university in 2020, gave an oral presentation titled "Standard silicon technology in the era of the next generation gravitational wave detectors" and was awarded the Excellent Report Award.
Jin Shangjie reported on a series of work completed in collaboration with his mentor Professor Zhang Xin. The research results are based on the expected design indicators of the 2.5th generation ground gravitational wave detector, considering three gravitational wave observation strategies, and predicting the ability of the gravitational wave standard whistle in cosmological parameter estimation during the 2.5th generation detector era, especially the potential to help solve the current cosmological problem of "Hubble tension"; a network of "Taiji----Tianqin---- LISA" space gravitational wave detectors was proposed for observation, predicting the positioning and detection capabilities for the merger of massive double black holes, and conducting cosmological analysis based on simulated standard whistle data. Research has found that future observations of gravitational wave standard whistles are expected to help solve major cosmological challenges.
At the closing ceremony of the conference, Academician Cai Ronggen, President of the Gravitation and Relativistic Astrophysics of the Chinese Physical Society and President of Ningbo University, and Professor Zhang Zhuozhua, President of University of South China, presented certificates of awards to the seven students who won the Excellent Report Award.
