abstract:
Based on the photometric and spectroscopic data from the GAMA survey, the star formation quenching of the local Universe galaxies was analyzed. The study of the sSFR surface spread on the D4000 versus the stellar mass plane shows two quenching channels. The horizontal one transfers the majority of blue galaxies into the red sequence. Whereas the bulge-dominated small active galaxies cross the vertical channel.
