Radial profiles of AC114. Top panel: stellar masses of galaxies as a function of the clustercentric radius. Blue and red crosses are SF and passive galaxies. Black diamonds represent mean mass bins of ∼23 h⁻¹ Mpc. Black, blue, and red lines are the linear fits that show a negative mass-gradient as a function of the clustercentric radius for the complete sample, SF, and passive galaxies, respectively. Bottom panel: metallicity profile of the SF galaxies with available mean metallicity estimations. Black diamonds are mean metallicities in bins of ∼33 h⁻¹ Mpc, and the black line is the linear fit that shows a weak negative gradient.
