LIGO S5对残余引力波的限制
残余引力波 宇宙学 暴涨
2011/9/25
由于LIGO探测器已经达到了其设计灵敏度，其最新的S5数据可以用来实现对于残余引力波的限制。残余引力波产生于暴涨期间，其解析谱对初始条件极为敏感，而初始条件主要由指数 、跑动谱指数 和张量-标量比 来描述。利用LIGO S5的两台探测器数据的交叉关联，我们得到了对参数 的限制。其中一个主要结果，利用LIGO给定的一对探测器的交叉关联，我们计算出对于不同的参数 情况下的残余引力波的信噪比值。同时，还...
Hierarchical Hough all-sky search for periodic gravitational waves in LIGO S5 data
Hierarchical Hough LIGO S5 data periodic gravitational waves
2010/3/18
We describe a new pipeline used to analyze the data from the fifth science run (S5) of the LIGO detectors to search for continuous gravitational waves from isolated spinning neutron stars. The method ...
We present data on the modulation of the dark port power at the free spectral range frequency of the LIGO 4 km interferometers. It is found that the power is modulated exactly at the tidal frequencies...
