Table A.1.

Parameters used to describe the EAGLE-like and TNG-like MS galaxies

Parameter	EAGLE	TNG100
k $_{CCNS} [M_{⊙}^{- 1}]$ $_{\mathrm{CCNS}} [{M}_{\odot}^{-1}]$	0.017 [1]	0.0118 [2]
N $_{Ia 0} [M_{⊙}^{- 1}]$ $_{\mathrm{Ia0}} [{M}_{\odot}^{-1}]$	2 ⋅10⁻³ [1]	1.3 ⋅10⁻³ [2]
m $_{Fe}^{Ia} [M_{⊙}$ $^{\mathrm{Ia}}_{\mathrm{Fe}} \ [{M}_{\odot}$ ]	0.74 [1]	0.74 [2]
m $_{Fe}^{CCSN} [M_{⊙}$ $^{\mathrm{CCSN}}_{\mathrm{Fe}} \ [{M}_{\odot}$ ]	0.04	0.04
[O/Fe]_CCSN	0.68	0.58
m $_{O}^{CCSN} [M_{⊙}$ $^{\mathrm{CCSN}}_{\mathrm{O}} \ [{M}_{\odot}$ ]	0.96	1.2
f_Ia	∝ e^−t/2Gyr [1]	∝ t^−1.12 [3]

Notes. Parameters of Equation 1 used to model the tracks of EAGLE-like and TNG-like MS galaxies in the [O/Fe] – sSFR plane in Figure 4. m $_{Fe}^{CCSN}$ $^{\mathrm{CCSN}}_{\mathrm{Fe}}$ and [O/Fe]_CCSN were chosen to match the relation followed by the simulated galaxies (see text), which defines m $_{O}^{CCSN}$ $^{\mathrm{CCSN}}_{\mathrm{O}}$ . The remaining parameters come from the settings of the cosmological simulations.
