27 Jan 2022 — In three papers recently submitted to the arXiv, the LIGO, Virgo and KAGRA Collaborations present the results of new searches for continuous gravitational waves: long-duration signals from astrophysical sources with a slowly-evolving frequency. These searches were carried out on data from our third Observing Run (O3). The three papers focus on:
- Narrow-band searches for continuous and long-duration transient gravitational waves from known pulsars in our galaxy [arXiv paper] [science summary]
- All-sky searches for rotating neutron stars which are not associated with known pulsars [arXiv paper] [science summary]
- Searches for a “wandering” continuous wave signal from low-mass X-ray binary Scorpius X-1 [arXiv paper] [science summary]
Although no gravitational waves were found from these searches, our results improve the upper limits on signals from these astrophysical sources.
