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.

宇宙上的一个新窗口最近通过Ligo Reveration Wave Waber观测值检测到重力波。其他望远镜观察到电磁波（包括可见光），这个新窗口将为我们提供完全不同和互补的信息。这里描述的工作旨在更好地了解如何从这些引力波观察中获取最多信息。特别是，我们研究了中子星和黑洞的非常暴力的合并，以确定这些系统的性质如何在引力和电磁波中编码。该奖项支持的目标是研究紧凑物体的动态以及它们发出的辐射，以捕获阿里戈和类似探测器的最大科学。我们将通过二元系统的计算研究，这些系统结合了具有电阻效应的磁化物，状态的逼真方程，电磁和中微子发射以及R过程核合成。我们的努力将包括以下内容：（i）我们将确定这些二进制文件的重力波形，重点是来自状态，质量和半径的中子星方程的可观察烙印。 （ii）我们将研究分析和现象学重力波模板的构建。 （iii）我们将研究合并二进制文件的流出，作为具有特征电磁和中微子信号的事件的指标。 （iv）我们将研究磁场和电磁排放的全球行为，例如喷气机，它们起源于融合二进制的磁层。
