Results from the First All-Sky Search for Continuous Gravitational Waves from Small-Ellipticity Sources.

We present the results of an all-sky search for continuous gravitational-wave signals with frequencies in the 500-1700 Hz range targeting neutron stars with ellipticity of 10^{-8}. The search is done on LIGO O2 data using the Falcon analysis pipeline. The results presented here double the sensitivity over any other result on the same data [B.

Sensitivity Improvements in the Search for Periodic Gravitational Waves Using O1 LIGO Data.

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.
