Inflation after Planck and BICEP2
  We discuss the inflationary paradigm, how it can be tested, and how various
models of inflation fare in the light of data from Planck and BICEP2. We
introduce inflation and reheating, and discuss temperature and polarisation
anisotropies in the cosmic microwave background radiation due to quantum
fluctuations during inflation. Fitting observations of the anisotropies with
theoretical realisations obtained by varying various parameters of the
curvature power spectrum and cosmological parameters enables one to obtain the
allowed ranges of these parameters. We discuss how to relate these parameters
to inflation models which allows one to rule in or out specific models of
inflation.
