  A double inflationary model with enhanced power at large scales --- Broken
Scale Invariant perturbations (BSI) --- leads to a promising scenario for the
formation of large-scale structure. We use high-resolution PM simulations with
a model for the thermodynamic evolution of baryons. Galactic halos are
identified as peaks in the distribution of mass points which had time to cool
providing a physical biasing mechanism. The clustering properties of galactic
halos are in agreement with both small-scale and large-scale characteristics of
the galaxy distribution, as variances of counts in cells, 'galaxy' correlation
functions, 'cluster' abundances and 'cluster-cluster' correlation functions,
and velocity dispersions at small scales.
