Top: The MZR for the ‘No SFR dependence’ case toy model with three different MZR parameters. We also plot our direct-T_e metallicity estimates. Bottom: Specific star formation rate (sSFR) as a function of gas-phase metallicity. We show sSFR vs. gas-phase metallicity for our Hγ stellar mass binned stacks. The error bars on the sSFR are calculated using the 16th and 84th percentile in the stacks. The panels on the left are following the parameters by Curti et al. (2024), the middle panels follow the parameters by Heintz et al. (2023) and the panels on the right follow paramters by Sarkar et al. (2025) for Eq. 4.
