Continuous gravitational waves from neutron stars: current status and prospects [HEAP]

http://arxiv.org/abs/1909.12600


Gravitational waves astronomy allows us to study objects and events invisible in electromagnetic waves. It may be 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 in neutron stars, like 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). Astrophysical motivation for continuous gravitational waves searches, current LIGO and Virgo strategies of the data analysis and future prospects are reviewed in this work.
