A general approach for testing non-cold dark matter at small
  cosmological scales
  We present a general approach for modelling the small-scale suppression in
the linear matter power spectrum induced by the presence of non-cold dark
matter. We show that the new parametrisation accurately describes a large
variety of non-thermal scenarios, removing the need to individually test each
of them. We discuss the first astrophysical constraints on its free parameters
and we outline the next steps for pursuing a full statistical data analysis.
