Central gas velocity dispersion σ_gas, c as a function of stellar mass of the galaxy M_sp (panel a), central surface brightness in the Hα line Σ_Hα, C (panel b), and central surface brightness in the [O III]λλ4959,5007 emission lines Σ_OIII, C (panel c). Galaxies with the circumnuclear regions of the AGN-type are denoted by red crosses, INT-type by green plus symbols, and SF-type by blue circles. The line in panels b and c is the demarcation line between the location of galaxies with the circumnuclear regions of the AGN and SF-types.
