Abstract

In the local universe dwarf galaxies represent 80% of the overall galaxy population, while their type-distribution (passive, early- vs. star-forming, late-type dwarfs) depends on galaxy density (i.e. morphology-density relation). However, the details of the processes governing these transformations are still not well understood. This project aims to unveil these processes using surface photometry of a large sample of late-type galaxies from SDSS in combination with evolutionary synthesis models. We derive structural properties and compare them with other data and model predictions.
