Structure and evolution of nearby galaxies
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.
