Tensorial Perturbations in an Accelerating Universe
arXiv:gr-qc/0304071 · doi:10.1023/A:1020026818125
Abstract
We study tensorial perturbations (gravitational waves) in a universe with particle production (OSC). The background of gravitational waves produces a perturbation in the redshift observed from distant sources. The modes for the perturbation in the redshift (induced redshift) are calculated in a universe with particle production.
