Elliptical galaxies: structure and stellar content

In this thesis, radial colour and line strength gradients are investigated, and corresponding stellar population gradients are modelled. Together with the gradients, the morphology of the galaxies in optical and near-infrared colours is analyzed. When investigated in detail, every elliptical galaxy has its own special morphology, but nevertheless the class of ellipticals has a large number of properties in common. We will list here the most important conclusions of this work ... .... Zie: Summary
