在S4资料中寻找周期引力波的全天空LIGO研究报告

Report on an all-sky LIGO search for periodic gravitational waves in the S4 data

Alicia M. Sintes

摘要:

我们报告的全天空搜索周期性引力波的频率范围为50-1000赫兹,并具有负频率时间导数与幅度之间的零和$10^{-8}$ Hz/s的LIGO探测器。来自第四次LIGO科学运行的数据已用于此搜索。三种不同的半相干方法的总和应变功率。没有观察到周期性引力辐射的证据,我们报告的上限应变振幅和解释这些限制,以约束辐射旋转中子星。

英文摘要:

We report on an all-sky search with the LIGO detectors for periodic gravitational waves in the frequency range 50-1000 Hz and having a negative frequency time derivative with magnitude between zero and $10^{-8}$ Hz/s. Data from the fourth LIGO science run have been used in this search. Three different semi-coherent methods of summing strain power were applied. Observing no evidence for periodic gravitational radiation, we report upper limits on strain amplitude and interpret these limits to constrain radiation from rotating neutron stars.
