Continuous gravitational-wave signals (CWs), emitted by rapidly rotating neutron stars with non-axisymmetric deformations, are compelling targets for the Advanced LIGO-Virgo-KAGRA detectors. These dense, compact objects possess strong magnetic fields and emit electromagnetic radiation from hotspots near the poles or from the magnetosphere. Observation of CWs from a neutron star would yield crucial insights into the star’s structure and its equation of state.
In this presentation, I will explain how the LIGO-Virgo-KAGRA collaboration aims to detect these signals and discuss the most recent results.
