Abstract
We present the results of an all-sky search for continuous gravitational wave
signals with frequencies in the 1700-2000 Hz range from neutron stars with
ellipticity of 1e-8. The search employs the Falcon analysis pipeline on LIGO O2
public data. Our results improve by a factor greater than 5 over [citation 5].
Within the probed frequency range and aside from the detected outliers, we can
exclude neutron stars with ellipticity of 1e-8 within 65 pc of Earth. We set
upper limits on the gravitational wave amplitude that hold even for worst-case
signal parameters. New outliers are found, some of which we are unable to
associate with any instrumental cause. If any were associated with a rotating
neutron star, this would likely be the fastest neutron star today.
