LIGO, VIRGO, AND KAGRA RELEASE NEW RESULTS FROM SEARCHES FOR LONG-DURATION GRAVITATIONAL-WAVES BURSTS

30 Jul 2021 — In a paper recently submitted to the arXiv, the LIGO, Virgo, and KAGRA Collaborations released the results of searches for long-duration gravitational waves in data from the detectors’ third Observing Run. The techniques used to search for these signals are designed to make minimal or no assumptions, which enables the detection of signals from a wide range of potential sources. Although no detections were found, our results improve—by about a factor of two—limits on the rate of eccentric binary coalescences occurring in the universe.
