1 Dec 2021 — While our catalog of transient gravitational wave events from compact binaries keeps growing, the LIGO, Virgo, and KAGRA Collaborations are also searching for other types of astrophysical signals. In three papers recently submitted to the arXiv, we have placed new constraints on continuous gravitational waves from various source classes. Continuous gravitational-waves are long-duration signals with a slowly-evolving frequency. The source classes constrainted in these studies involved:
- Targeted searches for signals from 236 known pulsars. [arXiv paper] [science summary]
- Wide parameter space searches for signals from two famous supernova remnants. [arXiv paper] [science summary]
- A search for signals from dark matter clouds (scalar bosons) around spinning black holes. [arXiv paper] [science summary]
