This paper evaluates and compares the gravitational wave and density perturbation contributions to the cosmic microwave background radiation, on the basis of the same power law inflationary model. The inflation to radiation transition is treated as instantaneous, but a model is constructed to allow for a smooth transition from the radiation to the matter dominated eras. The equations are numerically investigated and integrated, without any basic approximations being made. Use is made of the… Expand

Post-inflationary reheating and perturbations of the cosmic microwave background
We formulate a gradual dynamical transition from a power-law inflation era with a scalar field to a radiation era with no scalar field including inhomogeneous perturbations to the Friedmann-Expand

This paper presents a systematic treatment of the linear theory of scalar gravitational perturbations in the synchronous gauge and the conformal Newtonian (or longitudinal) gauge. It differs fromExpand
Models of inflation and the spectral index of the density perturbation
If an adiabatic density perturbation is responsible for large scale structure and the cmb anisotropy, its spectral index n will be measured in the forseeable future with an accuracy ∆n ∼ .01. This isExpand
