Description
For low-redshift quasars, growing observational evidence supports secular processes and minor mergers as the dominant mechanisms for nuclear triggering. We present results from a recently accepted paper based on the GAMA spectroscopic survey, in which we investigate the star formation histories of quasar host galaxies using SED fitting. We also present preliminary results from a companion paper in preparation that examines the host-galaxy morphologies of the same quasar sample. Galaxy morphologies were visually classified following the Hubble sequence, and structural properties were quantified using Sérsic indices derived from GALFIT modeling. In all analyses, the GAMA data enable the construction of a control sample of inactive galaxies matched in redshift and stellar mass, allowing for a robust comparison between active and inactive systems.
