dc.description.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 ] × 1 0 − 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 h 0 is ∼ 4 × 1 0 − 25 near 170 Hz, while at the high end of our frequency range, we achieve a worst-case upper limit of 1.3 × 1 0 − 24 . For a circularly polarized source (most favorable orientation), the smallest upper limit obtained is ∼ 1.5 × 1 0 − 25 . en_US
