讲座地点:齐云楼525报告厅
讲座题目:Numerical Relativity, Gravitational wave form models and Gravitational Wave detection
讲座摘要:LIGO has anounced three detected gravitational wave events and one to be confirmed event. All four sources are binary black hole systems. In order to support the state of art gravitational wave data analysis technique, matched filtering, people need gravitational wave form models. Aided with proper gravitational wave form model, the detection ability of gravitational wave will be strongly enhanced. And more, the gravitational wave form model provids us the necessary condition to extract the information of the gravitational wave source. Currently, the most matured gravitational wave form models are the ones for binary black hole. Among the models for binary black hole, the most complete ones include the EOBNR model and the Phenom model. In this talk I will review these two models and discuss related problems.
个人简介:曹周键,北京师范大学天文系教授,中国科学院数学与系统科学研究院副研究员,2016年国家自然科学基金“优秀青年科学基金(优青)”获得者。2006年北京师范大学博士毕业后致力于数值相对论和引力波物理的理论研究。先后在台湾成功大学和德国耶拿大学分别留学一年。短期访问过德国马普引力所、美国布朗大学、日本京都大学等。在数值相对论方面,与合作者一起发展了Z4c数值相对论计算方程形式,为高自旋双黑洞发展了高精度计算方法,开发出数值相对论软件AMSS-NCKU。在引力波理论方面,发展了BS理论框架到带宇宙学常数的爱因斯坦方程,建立了双黑洞系统的若干引力波理论模型。
