The SFMS for a comparison sample of low-redshift ring galaxies (R. Shimakawa et al. 2024) and a selected sample of high-redshift ring galaxies (T. Yuan et al. 2020; D. Liu et al. 2023; A. Nestor Shachar et al. 2025; M. Perna et al. 2025), including the galaxy studied in this work. We use the parameterized main sequences from P. Popesso et al. (2023) for further comparison. We find that observed high-redshift ring galaxies to date have much higher SFRs than their lower-redshift analogs, and lie on or above the SFMS at z = 2–4.
