| Abstract: |
Stochastic backgrounds of gravitational waves would be cosmological gold mine to probe the very early universe beyond last scattering surface of photon. In this talk, starting with a brief introduction on how to detect and characterize gravitational-wave backgrounds (GWBs), I will show that a network of ground-based detectors has a potential to tightly constrain the polarization states of GWBs. Prospect for direct detection of GWBs from space will be also discussed, and I will give a comment on another benefit for cosmological science, together with a required sensitivity for space interferometer. |
