Early release of low-frequency atlas of continuous gravitational waves (2507.12161v1)

Abstract: We present the public release of the low-frequency atlas of continuous gravitational waves, covering signals with frequencies from 20 Hz to 200 Hz and frequency derivatives from -5e-11 to 5e-11 Hz/s. Compared to the previous atlas releases, this version demonstrates significant improvements in sensitivity and sky resolution. In the most sensitive region even the worst-case upper limits on gravitational wave strain are below 1e-25. The atlas data is being released ahead of the completion of the full follow-up analysis.
