Title:  低频引力波天文学(Low frequency gravitational wave astrophysics)

Abstract: 报告讨论了多种低频引力波源，特别是极端质量比旋进系统的动力学过程和数值模拟，介绍了地面和未来空间引力波探测器对此类引力波源的观测以及波形模版的构建。报告还讨论了极端质量比旋进系统的低频引力波在暗物质、致密天体状态方程、基本物理检验等天文学和物理学上的重要应用。

Title:  Analogue gravity versus real gravity

Abstract: Although analogue gravity appeared in non-gravitational systems show many features resemble to real gravitational systems such as the appearance of curved geometry and horizon, their underlying dynamics look rather different from that of the real gravity and hence they were merely treated as analogous models from the conventional viewpoint. However, in this talk, we will show that, the two systems can indeed be connected with each other from a holographic viewpoint. We will give three examples to illustrate their connection.
