We study the morphology and kinematics of the ionization state of the gas in four ‘green valley’ early-type galaxies at different stages of their transition from a ‘blue cloud’ of star-forming galaxies to the sequence of passive evolution. The previous Hi mapping of the considered sample reveals a spatial offset between the cold gas reservoirs and stellar discs depending on the post-starburst age. Consideration of the ionized-gas properties is essential to understand the role of various feedback processes in star formation quenching.
