Résumé |
Quasi-monochromatic, quasi-infinite duration gravitational-wave signals,
i.e. continuous gravitational waves, represent one of the many types of
signals that have yet to be detected by LIGO, Virgo and KAGRA. Though they
are modelled rather simply compared to signals from binary black hole and
neutron star mergers, the inherent weakness of continuous waves, as well as
the large parameter space over which we must search, have made detecting
these signals a major challenge. In this talk, I will describe the possible
sources of continuous gravitational waves, e.g. isolated neutron stars,
depleting boson clouds around black holes, and primordial black hole
inspirals, and the data analysis principles and techniques used to search
for these sources. I will also present recent constraints from continuous
gravitational-wave searches, and comment on the prospects of detecting these
signals in future observing runs and with future detectors. |
