Early release of low-frequency atlas of continuous gravitational waves

TL;DR

This paper announces the public release of a low-frequency gravitational wave atlas, showcasing improved sensitivity and resolution in the 20-200 Hz range, with strain limits below 1e-25, ahead of full follow-up analysis.

Contribution

It provides the first comprehensive low-frequency gravitational wave atlas with enhanced sensitivity and sky resolution compared to previous versions.

Findings

Sensitivity improved significantly over previous releases

Strain upper limits below 1e-25 in the most sensitive regions

Atlas covers 20-200 Hz frequency range with detailed sky resolution

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.
