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]Ã—10-8 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 âˆ¼4Ã—10-25 near 170 Hz, while at the high end of our frequency range, we achieve a worst-case upper limit of 1.3Ã—10-24. For a circularly polarized source (most favorable orientation), the smallest upper limit obtained is âˆ¼1.5Ã—10-25.
