Constraints on single entity driven inflationary and radition eras
  We present a model that attempts to fuse the inflationary era and the
subsequent radiation dominated era under a unified framework so as to provide a
smooth transition between the two. The model is based on a modification of the
generalized Chaplygin gas. We constrain the model observationally by mapping
the primordial power spectrum of the scalar perturbations to the latest data of
WMAP7. We compute as well the spectrum of the primordial gravitational waves as
would be measured today.
