要旨

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.
