Structure and evolution of nearby galaxies

Edyta Biskupska and Janusz Krywult

Using GAMA photometric and morphology data, we studied the structure and evolution of galaxies in redshift z<0.5. Based on u−r rest-frame colour versus the Sérsic index plane, galaxies were divided into early- and late-type populations. The analysis show evolution of the u−r colour and Sérsic index and the strong correlation between these parameters indicating that the galaxy mergers are the main driving mechanism transforming disk-like galaxies into ellipticals.
