我们提出了计算相对论（Core）合作的公共数据库的引力波形从双中子星星合并。该数据库目前包含367个波形，这些波形来自符合广义相对论的数值模拟，并采用满足流体动力学平衡初始数据的约束。它跨越164个物理上不同的配置，具有不同的二元参数（二元总质量、质量比、初始分离、偏心率和恒星自旋）和模拟物理。提供了在多个网格分辨率和提取半径下计算的波形，以控制数值不确定性。我们还发布了一组示例性的18个混合波形，这些波形是用最先进的有效单体模型构建的，跨越了先进的引力波探测器的频带。我们概述了目前和未来的应用程序的数据库引力波天文学。
We present the computational relativity (CoRe) collaboration’s public database of gravitational waveforms from binary neutron star mergers. The database currently contains 367 waveforms from numerical simulations that are consistent with general relativity and that employ constraint satisfying initial data in hydrodynamical equilibrium. It spans 164 physically distinct configuration with different binary parameters (total binary mass, mass-ratio, initial separation, eccentricity, and stars’ spins) and simulated physics. Waveforms computed at multiple grid resolutions and extraction radii are provided for controlling numerical uncertainties. We also release an exemplary set of 18 hybrid waveforms constructed with a state-of-art effective-one-body model spanning the frequency band of advanced gravitational-wave detectors. We outline present and future applications of the database to gravitational-wave astronomy.
