Collaborative Research: Compact Binary Mergers in the Advanced LIGO Era

最近，随着LIGO引力波天文台对引力波的探测，打开了一扇新的宇宙之窗。其他望远镜观察电磁波（包括可见光），这个新窗口将为我们提供完全不同的互补信息。这里描述的工作旨在更好地理解如何从这些引力波观测中获得最多的信息。特别是，我们研究中子星和黑洞的非常剧烈的合并，以确定这些系统的属性是如何被编码在引力波和电磁波中的。该奖项支持的目标是研究紧凑物体的动力学和它们发出的辐射，以便从aLIGO和类似探测器中捕获最多的科学可能。我们将通过结合磁化物质与电阻效应，现实的状态方程，电磁和中微子发射，和r-过程核合成的二进制系统的计算研究。我们的努力将包括以下内容：（i）我们将确定这些双星的引力波形，重点是中子星星状态方程、质量和半径的可观测印记。 (ii)我们将研究解析和唯象引力波模板的构造。(iii)我们将研究从合并双星流出的特征电磁和中微子信号事件的指标。(iv)我们将研究磁场和电磁辐射的全球行为，如射流，起源于合并双星的磁层。

A new window on the universe opened recently with the detection of gravitational waves by the LIGO gravitational wave observatory. Other telescopes observe electromagnetic waves (that includes visible light), and this new window will give us quite different and complementary information. The work described here seeks to understand better how to get the most information from these gravitational wave observations. In particular, we study the very violent merger of neutron stars and black holes to determine how the properties of these systems are encoded in both gravitational and electromagnetic waves.The goals supported by this award are to study the dynamics of compact objects and the radiation they emit to capture the most science possible from aLIGO and similar detectors. We will do so through computational studies of binary systems incorporating magnetized matter with resistive effects, realistic equations of state, electromagnetic and neutrino emission, and r-process nucleosynthesis. Our efforts will include the following: (i) We will determine gravitational waveforms from these binaries, with a focus on observable imprints from the neutron star equation of state, mass, and radius. (ii) We will investigate the construction of analytic and phenomenological gravitational wave templates. (iii) We will study outflows from merging binaries as an indicator of events with characteristic electromagnetic and neutrino signals. (iv) We will study the global behavior of magnetic fields and the electromagnetic emissions, such as jets, that originate in the magnetosphere of coalescing binaries.
