Query: Tautological classes on the moduli spaces of stable maps to projective
  spaces   We present a localization proof of the fact that the cohomology of the moduli
spaces of genus zero stable maps to projective spaces is entirely tautological.
In addition, we obtain a description of a Bialynicki-Birula stratification in
the context of Gathmann's moduli spaces of maps with prescribed contact order
to a fixed hyperplane.
