Gravitational waves astronomy allows us to study objects and events invisible in electromagnetic waves. It is crucial to validate the theories and models of the most mysterious and extreme matter in the Universe: the neutron stars. In addition to inspirals and mergers of neutrons stars, there are currently a few proposed mechanisms that can trigger radiation of long-lasting gravitational radiation from neutron stars, such as e.g., elastically and/or magnetically driven deformations: mountains on the stellar surface supported by the elastic strain or magnetic field, free precession, or unstable oscillation modes (e.g., the r-modes). The astrophysical motivation for continuous gravitational waves searches, current LIGO and Virgo strategies of data analysis and prospects are reviewed in this work.

  1. One-stop strategy to search for long-duration gravitational-wave signals

    gr-qc 2024-11 conditional novelty 6.0 of 10

    A generic GPU search engine plus a fast semianalytic sensitivity estimator could make blind continuous gravitational-wave searches much cheaper to run and characterize.

  2. Spotlight searches for continuous gravitational waves triggered on radiometer candidates in LIGO O4a data

    gr-qc 2026-08 accept novelty 5.0 of 10

    No continuous gravitational-wave signal was found in any of the 562 radiometer-triggered candidates after vetoes and an O4b follow-up; the search reaches 95% detection efficiency for strains around 0.63 to 6.3 times 10^-25.
