Now that detection of gravitational-wave signals from the coalescence of extra-galactic
compact binary star mergers has become nearly routine, it is intriguing to consider other …

Gravitational wave detectors are already operating at interesting sensitivity levels, and they
have an upgrade path that should result in secure detections by 2014. We review the …

Seven years after the first direct detection of gravitational waves, from the collision of two
black holes, the field of gravitational wave astronomy is firmly established. A first detection of …

We present results of an all-sky search for continuous gravitational waves (CWs), which can
be produced by fast spinning neutron stars with an asymmetry around their rotation axis …

Gravitational wave astronomy opened dramatically in September 2015 with the LIGO
discovery of a distant and massive binary black hole coalescence. The more recent …

Non-axisymmetrical deformations of the crust on rapidly rotating neutron stars are one of the
main targets of searches for continuous gravitational waves. The maximum ellipticity, or …

Significant progress has been made in recent years on the development of gravitational-
wave detectors. Sources such as coalescing compact binary systems, neutron stars in low …

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 …

We show that the Big Bang Observer (BBO), a proposed space-based gravitational-wave
(GW) detector, would provide ultraprecise measurements of cosmological parameters. By …

Gravitational wave science should transform in this decade from a study of what has not
been seen to a full-fledged field of astronomy in which detected signals reveal the nature of …
