Mass outflow rate versus SFR for our objects and low- and high-redshift galaxies, including stacking approaches at high redshift. The green and orange rectangles represent the range of possible values for AzTEC-3 and BRI0952, respectively. The low-z comparison sample is taken from Fluetsch et al. (2019), high-redshift direct observations are taken from Maiolino et al. (2012), George et al. (2014), Feruglio et al. (2017), Brusa et al. (2018), Herrera-Camus et al. (2019), Jones et al. (2019), Spilker et al. (2020), Butler et al. (2021), and high-redshift stacking averages are taken from Gallerani et al. (2018), Bischetti et al. (2019), Ginolfi et al. (2020). For Ginolfi et al. (2020), we plot the high-SFR sample and the median-SFR sample in their stacking methodology as separate points. We utilized an average of the mass outflow rates if a range is provided for an object.
