这是代表平行会议A3的贡献,关于修正的重力,在GR 20会议(2013年7月,华沙,波兰)的会议记录中。它由三个邀请章节组成,由会议主席(PH)选择。代表会议讨论的广泛主题,从理论和现象学到重力的实验、观测和数值方面。这三章分别是Arif Mohd的“Einstein-Aether Theory:Thermodynamics of Universal Horava-Lifshitz Gravity”,Charles M. Melby-Thompson和Peter Shawhan的“Detectability of Scalar Gravitational-Wave Bursts with LIGO and Virgo”。
英文摘要:
This is the contribution representing Parallel Session A3, on Modified Gravity, in the Proceedings of the GR 20 Conference (July 2013, Warszawa, Poland). It consists of three invited chapters, selected by the Session Chair (P.H.) to represent the broad spectrum of topics discussed in the Session, which ranged from theoretical and phenomenological, to experimental, observational and numerical aspects of gravity. The three chapters are "Einstein-Aether Theory: Thermodynamics of Universal Horizons" by Arif Mohd, "The Curious Case of Conformal Anomalies in Horava-Lifshitz Gravity" by Charles M. Melby-Thompson, and "Detectability of Scalar Gravitational-Wave Bursts with LIGO and Virgo" by Peter Shawhan.
Summary of GR18 Numerical Relativity parallel sessions (B1/B2 and B2), Sydney, 8-13 July 2007
GR 18的数值相对论会议主要是关于双黑洞合并的物理结果。从后牛顿运动方程仍然适用的时候开始,现在有几个研究小组可以模拟这些现象,通过几个轨道和合并到衰荡阶段,在无穷远处获得看似合理的引力波,并显示出一些收敛的证据。不同群体的结果大致一致。这些研究小组已经使用这种新获得的信心开始绘制问题的(有限维)初始数据空间,特别关注黑洞旋转的影响,以及最终合并黑洞的引力波反冲加速到数百公里/秒。其他的工作是在各种各样的主题,如物质的演变,极端的质量比的灵感,和技术问题,如规范的选择。
