论文摘要
诸如Lisa之类的未来检测器承诺在包含同时信号的数千个数据和数据中有可能信号噪声比率。准确的数值相对性波形对于最大化科学回报至关重要。广泛的引力浪潮社区的兴趣问题是：数值相对论是否准备面对这一挑战？为了回答这个问题，我们提供了一个新的标准，以确定模拟必须具有的最小分辨率作为信噪比的函数，以使数值相对性波形与真实信号没有区别。该标准可以应用于任何有限差异的数值相对论代码，并使用多个模拟所需的二进制参数和波形长度的分辨率进行了多个模拟。我们将此标准应用于第四阶Maya代码感兴趣的二进制系统，以获得对最低分辨率的第一个估计值，必须为下一代检测器准备模拟。
Future detectors such as LISA promise signal-to-noise ratios potentially in the thousands and data containing simultaneous signals. Accurate numerical relativity waveforms will be essential to maximize the science return. A question of interest to the broad gravitational wave community is: Are the numerical relativity codes ready to face this challenge? Towards answering this question, we provide a new criteria to identify the minimum resolution a simulation must have as a function of signal-to-noise ratio in order for the numerical relativity waveform to be indistinguishable from a true signal. This criteria can be applied to any finite-differencing numerical relativity code with multiple simulations of differing resolutions for the desired binary parameters and waveform length. We apply this criteria to binary systems of interest with the fourth-order MAYA code to obtain the first estimate of the minimum resolution a simulation must have to be prepared for next generation detectors.
