Query: Results from high-frequency 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 1700-2000 Hz range from neutron stars with
ellipticity of 1e-8. The search employs the Falcon analysis pipeline [citation
5] on LIGO O2 public data. Our results improve by a factor greater than 5 over
[citation 11]. This is a huge leap forward: it takes an entirely new generation
of gravitational wave detectors to achieve a 10-fold sensitivity increase over
the previous generation [citation 12]. 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.
