Gravitational wave background from magnetars
We investigate the gravitational wave background produced by magnetars. The statistical properties of these highly magnetized stars were derived by population synthesis methods and assumed to be also representative of extragalactic objects. The adopted ellipticity was calculated from relativistic models using equations of state and assumptions concerning the distribution of currents in the neut...
متن کاملGravitational Wave Background From Hybrid Topological Defects.
We investigate the spectrum of stochastic gravitational wave background generated by hybrid topological defects: domain walls bounded by strings and monopoles connected by strings. Such defects typically decay early in the history of the universe, and their mass scale is not subject to the constraints imposed by microwave background and millisecond pulsar observations. Nonetheless, the intensit...
متن کاملGravitational-wave stochastic background from cosmic strings.
We consider the stochastic background of gravitational waves produced by a network of cosmic strings and assess their accessibility to current and planned gravitational wave detectors, as well as to big bang nucleosynthesis (BBN), cosmic microwave background (CMB), and pulsar timing constraints. We find that current data from interferometric gravitational wave detectors, such as Laser Interfero...

متن کاملSearching for continuous gravitational wave sources in binary systems
We consider the problem of searching for continuous gravitational wave (CW) sources orbiting a companion object. This issue is of particular interest because, the Low Mass X-ray Binaries (LMXB’s), and among them Sco X-1 – the brightest X-ray source in the sky – might be marginally detectable with ≈ 2 years coherent observation time by the Earth-based laser interferometers expected to come on li...
