标题： Illuminating Gravitational Waves: A Concordant Picture of Photons from a Neutron Star Merger

摘要： 合并的中子星为同时研究强场引力和极端环境中的物质提供了一个绝佳的实验室。 我们确立了电磁对应体 EM170817 与从合并中子星探测到的引力波（GW170817）之间的物理关联。 通过合成多波段数据集，我们证明合并的中子星是通过r-过程核合成制造重元素的长期寻找的场所。 EM170817 中观察到的弱伽马射线与具有超高相对论喷流的经典短伽马射线暴不同。 相反，我们认为宽角、适度相对论的包层突破喷流可以优雅地解释低亮度伽马射线、高亮度紫外-光学-红外以及延迟的射电/ X 射线辐射。 我们认为所有合并的中子星可能会导致宽角包层突破；有时伴随成功的喷流，有时则是被阻塞的喷流。 显示英文摘要

摘要： Merging neutron stars offer an exquisite laboratory for simultaneously studying strong-field gravity and matter in extreme environments. We establish the physical association of an electromagnetic counterpart EM170817 to gravitational waves (GW170817) detected from merging neutron stars. By synthesizing a panchromatic dataset, we demonstrate that merging neutron stars are a long-sought production site forging heavy elements by r-process nucleosynthesis. The weak gamma-rays seen in EM170817 are dissimilar to classical short gamma-ray bursts with ultra-relativistic jets. Instead, we suggest that breakout of a wide-angle, mildly-relativistic cocoon engulfing the jet elegantly explains the low-luminosity gamma-rays, the high-luminosity ultraviolet-optical-infrared and the delayed radio/X-ray emission. We posit that all merging neutron stars may lead to a wide-angle cocoon breakout; sometimes accompanied by a successful jet and sometimes a choked jet.
