用高级LIGO数据对双星系统中未知中子星连续引力波信号的首次全天空搜索

First all-sky search for continuous gravitational-wave signals from unknown neutron stars in binary systems using Advanced LIGO data

P. B. Covas, Alicia M. Sintes

摘要:

旋转的中子星可以发出连续的引力波,目前还没有探测到。本文研究了轨道周期为15 ~ 45天的未知中子星双星系统中的连续引力波。这是先进的LIGO数据和最近开发的BinarySkyHough管道首次用于这种搜索。没有探测到的报告,并计算上限的引力波振幅,这改善了以前的结果的17倍。

英文摘要:

Rotating neutron stars can emit continuous gravitational waves, which have not yet been detected. We present a search for continuous gravitational waves from unknown neutron stars in binary systems with orbital period between 15 and 45 days. This is the first time that Advanced LIGO data and the recently developed BinarySkyHough pipeline have been used in a search of this kind. No detections are reported, and upper limits on the gravitational wave amplitude are calculated, which improve the previous results by a factor of 17.
