论文摘要

宇宙中绝大多数紧凑的二元合并产生的引力波太弱,无法产生明确的检测。他们尚未解决。我们提出了一种使用分辨率和未解决的重力波来推断紧凑型二进制文件的种群特性(例如它们的合并率,质谱和自旋分布)。通过完全消除分辨率和未解决的信号之间的区别,我们从选择效应中消除了偏见。为了证明这种方法,我们使用了以天体物理动机的二元黑洞人群进行蒙特卡洛研究。我们表明,在设计敏感性时与晚期Ligo进行了大约一周的观察后,紧凑型二进制文件的某些种群特性受到未解决的信号的限制。

The vast majority of compact binary mergers in the Universe produce gravitational waves that are too weak to yield unambiguous detections; they are unresolved. We present a method to infer the population properties of compact binaries -- such as their merger rates, mass spectrum, and spin distribution -- using both resolved and unresolved gravitational waves. By eliminating entirely the distinction between resolved and unresolved signals, we eliminate bias from selection effects. To demonstrate this method, we carry out a Monte Carlo study using an astrophysically motivated population of binary black holes. We show that some population properties of compact binaries are well constrained by unresolved signals after about one week of observation with Advanced LIGO at design sensitivity.
