A recent open-access article published in @paspjournal.bsky.social utilizes the well-studied Star-forming Main Sequence and integrated Kennicutt–Schmidt Relations to characterize star formation in the low surface brightness regime of galaxies. iopscience.iop.org/article/10.1...

Left: the star-forming main sequence of the LSB galaxy sample and fitted linear regression (colored circles, solid red line) compared to the comparison sample and best fit (gray circles, solid black line). The standard intrinsic scatter (0.3 dex) is shown as the shaded red area. Right: the distribution of delta-MS or the deviation from the comparison sample star-forming main sequence best fit.
