متن کاملMapping the gravitational wave background
The gravitational wave sky is expected to have isolated bright sources superimposed on a diffuse gravitational wave background. The background radiation has two components: a confusion limited background from unresolved astrophysical sources; and a cosmological component formed during the birth of the universe. A map of the gravitational wave background can be made by sweeping a gravitational w...
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 کاملDirect searches for a cosmological stochastic gravitational wave background
LIGO has completed a series of observations searching for evidence of a stochastic gravitational wave background. There has been no detection to date. However the sensitivity of the observations is approaching the Big Bang nucleosynthesis bound. Future observations will provide information that bounds a number of early Universe models of stochastic gravitational waves.
