Paper day! "Fitting the Radial Acceleration Relation to Individual SPARC Galaxies" by our brilliant student Pengfei Li: arxiv.org/abs/1803.00022 A thread will follow! In arxiv.org/abs/1609.05917 and arxiv.org/abs/1610.08981 we show that baryons and dynamics are tightly linked in galaxies at a *local* level: the observed acceleration (from the gas rotation curve) correlates with that expected from the distribution of baryons (using Newton's law).
