Abstract: (APS)

We demonstrate a breakthrough in the capabilities of robust, broad-parameter space searches for continuous gravitational waves. With a large scale search for continuous gravitational waves on the O1 LIGO data, we prove that our Falcon search achieves the sensitivity improvements expected from the use of a long coherence length, while maintaining the computational expense within manageable bounds. On these data we set the most constraining upper limits in the gravitational wave amplitude in the band 100–200 Hz. We provide full outlier lists and upper limits near the 0-spin-down band suitable for analysis of signals with small spin-down such as boson condensates around black holes.
