我们提出了第一个分析的来自具有非进动自旋的双黑洞（BBH）的吸气-合并-振铃引力波形，这是基于完全广义相对论中晚期吸气、合并和振铃的描述。通过将吸气的后牛顿描述与一组数值相对论模拟相匹配，我们获得了具有少量物理参数的波形族。这些波形将使我们能够检测到BBH聚结的更大参数空间，包括相当一部分处于可比质量范围内的进动双星，从而显着提高预期检测率。
We present the first analytical inspiral-merger-ringdown gravitational waveforms from binary black holes (BBHs) with nonprecessing spins, that is based on a description of the late-inspiral, merger and ringdown in full general relativity. By matching a post-Newtonian description of the inspiral to a set of numerical-relativity simulations, we obtain a waveform family with a conveniently small number of physical parameters. These waveforms will allow us to detect a larger parameter space of BBH coalescence, including a considerable fraction of precessing binaries in the comparable-mass regime, thus significantly improving the expected detection rates.
