Abstract
We report on a new all-sky search for periodic gravitational waves in the frequency band 475–2000 Hz
and with a frequency time derivative in the range of (-1.0, +0.1)x10^(-8) Hz/s. Potential signals could be
produced by a nearby spinning and slightly nonaxisymmetric isolated neutron star in our Galaxy. This
search uses the data from Advanced LIGO’s first observational run O1. No gravitational-wave signals were
observed, and upper limits were placed on their strengths. For completeness, results from the separately
published low-frequency search 20–475 Hz are included as well. Our lowest upper limit on worst-case
(linearly polarized) strain amplitude h0 is ∼4 × 10−25 near 170 Hz, while at the high end of our frequency
range, we achieve a worst-case upper limit of 1.3 × 10−24. For a circularly polarized source (most favorable
orientation), the smallest upper limit obtained is ∼1.5 × 10−25.
