Comparison between the sizes of Hα and those of the rest-frame FIR continuum. Our sample of SMGs are plotted with filled symbols along with their IDs, which have their field names removed for clarity. Sources that are identified to host an AGN are marked with an asterisk after the ID. We also plotted the measurements, which were were recently presented by Nelson et al. (2019), of a starburst galaxy at z = 1.25 with an empty symbol. Based on our sample of SMGs, we find on a median Hα-to-FIR size ratio of 2.0 ± 0.4 with a bootstrapped uncertainty.
