Effect of different nucleosynthesis yields for massive stars (panels a and c) and AGB stars (panels b and d) on the predicted Y vs. Z relation from a one-zone galaxy chemical evolution model with star formation efficiency SFE = 2 Gyr⁻¹, infall timescale τ = 4 Gyr, and no galactic winds. For massive stars we explore the stellar yields of Nomoto et al. (2013), which are adopted in our cosmological simulations, and the stellar yields of Limongi & Chieffi (2018) for different stellar rotational velocities (v0, v150 and v300 represent rotational velocity v = 0, 150, and 300 km s⁻¹, respectively). For AGB stars, we explore the stellar yields of Karakas (2010), adopted in our cosmological simulations, and those of Ventura et al. (2013); see also e.g. Vincenzo et al. (2016).
