活动简介：As ground‑based gravitational‑wave detectors continue to uncover an increasing number of novel and significant gravitational‑wave events, gravitational‑wave astronomy is developing at a rapid pace. Coupled with the successful missions of LISA Pathfinder, Taiji‑1 and Tianqin‑1, a growing number of nations and research teams are ramping up investment in space‑based gravitational‑wave detection. At present, the European‑American LISA space gravitational‑wave mission has been formally approved. China’s Taiji and Tianqin programmes, together with Japan’s DECIGO, are also being actively advanced. Against this backdrop of fruitful cooperation and competition among these four projects, space‑based gravitational‑wave detectors are expected to commence operation in ten years’ time. Gravitational‑wave theoretical templates constitute a vital theoretical foundation for gravitational‑wave data processing, while numerical relativity serves as the core technique for constructing such templates. This report will present to the audience the recent and future advances in gravitational‑wave astronomy, as well as numerical‑relativity techniques and their role in gravitational‑wave data analysis.
