Oscillons from Pure Natural Inflation
  We examine the oscillon formation in a recently proposed inflation model of
the pure natural inflation, where the inflaton is an axion that couples to a
strongly-coupled pure Yang-Mills theory. The plateau of the inflaton potential,
which is favored by recent observations, drives the fragmentation of the
inflaton and can produce spatially localized oscillons. We find that the
oscillons are formed for F<~ O(0.1) M_{Pl}, with F the effective decay constant
of the model. We also comment on observational implications of the oscillons.
