Abstract
We present the results of an all-sky search for continuous gravitational wave signals with frequencies in the 200-600 Hz range and frequency derivative (spindown) from-1×10-8 through 1.11×10-9 Hz/s. Together with the results from [V. Dergachev and M. A. Papa Phys. Rev. Lett. 123, 101101 (2019)PRLTAO0031-900710.1103/PhysRevLett.123.101101], this search completes the all-sky survey for frequencies between 20 to 600 Hz on O1 data. It also demonstrates the scalability of our search on a parameter space 26 times larger than previously considered. The results presented here complement the LIGO O2 data results [C. Palomba Phys. Rev. Lett. 123, 171101 (2019)PRLTAO0031-900710.1103/PhysRevLett.123.171101, B. P. Abbott Phys. Rev. D 100, 024004 (2019)PRVDAQ2470-001010.1103/PhysRevD.100.024004] with comparable when not better sensitivity and do not rely on data with irregularities in the noise-subtraction procedure. We establish strict upper limits which hold for worst-case signal parameters and dedicated upper limits for generic ≈0 spindown signals, such as those expected from boson condensates around black holes.
