Predicting Metallicities and Color Distributions for Secondary GCs Forming in Spiral Galaxy Mergers at Various Redshifts

In a 1st step I present results from our new set of evolutionary synthesis models for Simple (= single burst) Stellar Populations (SSPs) of various metallicities, and in a 2nd step I combine these results with the information we have about the redshift evolution of spiral galaxies’ ISM abundances. The aim is to provide a grid of color and luminosity distibutions of any secondary GC population formed at some time in the past in those mergers for comparison with observations.
