Comoving SFRD as a function of time and redshift in four different boxes of the MTNG simulations, as indicated in the legend. The determinations of the cosmic SFRD as reported in Madau & Dickinson (2014) and Driver et al. (2018) are also shown for comparison. Owing to the constant mass resolution of the analyzed MTNG boxes, the SFRD is well-converged, with negligible differences among the runs. The MTNG SFRD peaks at earlier redshifts (z ∼ 3, rather than z ≈ 2) and shows a less steep decline toward lower redshift compared to the results presented in Madau & Dickinson (2014). Overall, the SFRD values in MTNG are broadly consistent with the determinations of Madau & Dickinson (2014) and Driver et al. (2018), although they tend to be lower by up to a factor of ≲ 2 in the redshift range z ∼ 1–2.
