摘要:

RIT数值相对论小组正在发布第二个公开的黑洞二元波形目录\url{http://ccrg.rit.edu/~RITCatalog}。该版本包括320个精确的模拟,其中包括46个进动和274个非进动双星系统,质量比$q=m_1/m_2$在$1/6\leq q\leq1$范围内,单个自旋高达$s/m^2=0.95$。新的目录包含搜索和排序工具的波形的基础上的初始参数的二进制,轨迹信息,峰值辐射,和最终残余黑洞的属性。这里提供的最终黑洞残余物的性质可以用来模拟黑洞双星从其初始配置的合并。波形外推到无限的观察者的位置,可以用来独立地解释引力波信号从激光干涉探测器。作为此波形目录的应用程序,我们重新分析的信号GW150914实施参数估计技术,只利用数值波形没有任何参考的信息从现象学模型。

英文摘要:

The RIT numerical relativity group is releasing the second public catalog of black-hole-binary waveforms \url{http://ccrg.rit.edu/~RITCatalog}. This release consists of 320 accurate simulations that include 46 precessing and 274 nonprecessing binary systems with mass ratios $q=m_1/m_2$ in the range $1/6\leq q\leq1$ and individual spins up to $s/m^2=0.95$. The new catalog contains search and ordering tools for the waveforms based on initial parameters of the binary, trajectory information, peak radiation, and final remnant black hole properties. The final black hole remnant properties provided here can be used to model the merger of black-hole binaries from its initial configurations. The waveforms are extrapolated to infinite observer location and can be used to independently interpret gravitational wave signals from laser interferometric detectors. As an application of this waveform catalog we reanalyze the signal of GW150914 implementing parameter estimation techniques that make use of only numerical waveforms without any reference to information from phenomenological models.
