探测连续引力波的超爱因斯坦极化

Detecting Beyond-Einstein Polarizations of Continuous Gravitational Waves

Maximiliano Isi, Alan J. Weinstein, Carver Mead, Matthew Pitkin

摘要:

用下一代探测器直接探测引力波,如先进的LIGO,提供了测量与广义相对论预测偏差的机会。其中一种偏离是存在替代性极化。为了测量这些,我们研究了一个三轴脉冲星源的连续引力波的单探测器测量。我们开发的方法来检测任何偏振内容的信号,并在一个模型独立的方式来区分它们。我们提出了LIGO S5对115颗恒星的灵敏度估计。

英文摘要:

The direct detection of gravitational waves with the next generation detectors, like Advanced LIGO, provides the opportunity to measure deviations from the predictions of General Relativity. One such departure would be the existence of alternative polarizations. To measure these, we study a single detector measurement of a continuous gravitational wave from a triaxial pulsar source. We develop methods to detect signals of any polarization content and distinguish between them in a model independent way. We present LIGO S5 sensitivity estimates for 115 pulsars.
