Extended Data Fig. 4: Distribution of all the JQ clumps, and the entire JQ system in the star formation rate – stellar mass plane.
From: Extended enriched gas in a multi-galaxy merger at redshift 6.7
The red squares and red dots represent the best-fit values from the SED fitting, with the error bars showing the 16th and 84th percentiles of the distributions of 400 posteriors. The clump C16 with a very small SFR of \(0.00{5}_{-0.005}^{+0.057}{M}_{\odot }{{\rm{yr}}}^{-1}\) is marked by a red triangle. We also plot a series of measurements at similar redshifts from the literature and the best-fit SFMS relations based on those samples17,18,19,20. The error bars represent the 1σ confidence intervals. In all cases, the clumps in JQ with stellar masses \(\log {M}_{\star }/{M}_{\odot }\lesssim 9\) have SFRs more than 1 dex above the measured SFMS relation of ref. 17, indicating the clumps are in a bursting phase. The total SFR of galaxies in the JQ system is higher than the SFMS by ~ 1 dex and among the top SFR of the galaxies at similar redshifts.
