用螺旋模板搜索二元聚结:检测和参数估计

Searching for binary coalescences with inspiral templates: Detection and parameter estimation

Benjamin Farr, Stephen Fairhurst, B. S. Sathyaprakash

摘要:

近年来,数值相对论的研究取得了显著的进展.这导致了引力波形信号的产生,涵盖了传统上称为致密双星合并的三个阶段-螺旋,合并和环缩。在本文中,我们研究的有用性的inspiral只有模板的检测和参数估计的数值相对论模拟产生的全聚结波形。为此,我们部署作为搜索模板波形的基础上终止于光环以及标准后牛顿波形的有效单体波形。我们发现,这两个都是很好的信号检测。参数估计在低质量时是好的,但随着二元系统质量的增加而退化。

英文摘要:

There has been remarkable progress in numerical relativity recently. This has led to the generation of gravitational waveform signals covering what has been traditionally termed the three phases of the coalescence of a compact binary - the inspiral, merger and ringdown. In this paper, we examine the usefulness of inspiral only templates for both detection and parameter estimation of the full coalescence waveforms generated by numerical relativity simulations. To this end, we deploy as search templates waveforms based on the effective one-body waveforms terminated at the light-ring as well as standard post-Newtonian waveforms. We find that both of these are good for detection of signals. Parameter estimation is good at low masses, but degrades as the mass of the binary system increases.
