Gravitational Wave Background

We discuss possible anisotropic and inhomogeneous phases in the early Universe at relatively late epochs corresponding to the temperatures 1 GeV –10 TeV . The anisotropy and inhomogeneity of the energy-momentum tensor at the horizon scale gives rise to the generation of a stochastic gravitational wave background. It is shown that the present amplitudes and frequencies of this background may be well within the access of planned gravitational wave detectors.

Gravitational Wave Detectors

The gravitational wave detectors especially LIGO has attained its design sensitivity and up gradation has virtually reached near the completion. The gravitational wave search is in progress and hopefully result will be possible in due course of time.We discuss the recent attempts to detect various classes of signals which include un-modelled sub second burst of gravitational radiation like from core collapse supernoval and γ-ray burst engine. A stochastic background of gravitational waves of cosmological origin would provide a new idea about early universe. We discuss current attempts to detect gravitational waves from these sources and know about future prospectus of these searches.
