Generalized inflation with a gravitational wave background

We propose a Λ-inflation model that explains a significant part of the COBE signal by primordial cosmic gravitational waves. The primordial density perturbations fulfil both the constraints of large-scale microwave background and galaxy cluster normalization. The model is tested against the galaxy cluster power spectrum and the high-multipole angular cosmic microwave background anisotropy.

Observational constraints on Λ inflation

Observational data on the large-scale structure of the Universe and the anisotropy of the cosmic background radiation are used to derive constraints on the parameters of an inflationary model for the early Universe (Λ inflation).
