Abstract
A new loosely coherent analysis improves sensitivity to continuous gravitational waves by more than 30%, with order of magnitude gains in computational efficiency. Results of all-sky search in 20-200 Hz frequency band are provided including outlier lists and upper limits near 0-spindown band suitable for analysis of signals with small spindown such as boson condensates around black holes.
