Mass-metallicity relation at z > 9. Direct T_e metallicities and lower limits for the z > 9 sample are shown in hot pink and light pink, respectively, with the weighted mean and 1σ error of the sample indicated by the purple star. Various MZRs from literature are plotted (Heintz et al. 2023a; Curti et al. 2020; Morishita et al. 2024; Nakajima et al. 2023; Curti et al. 2024; Chemerynska et al. 2024; Chakraborty et al. 2025). Light grey scatter points represent the PRIMAL z = 3 − 10 sample, with circular grey markers and their associated solid black error bars being the median and 1σ error of stellar mass bins. The grey error bars represent the standard deviation of mass bins. The bold solid black line shows the best fit to the PRIMAL stellar-mass bins.
