Fig. 6: Kinematics and structure of GS-10578.
From: A fast-rotator post-starburst galaxy quenched by supermassive black-hole feedback at z = 3
a, \({\lambda }_{{{{R}}}_{{\rm{e}}}}\) versus ϵ diagram showing that, by interpreting the velocity field as stellar rotation, GS-10578 is supported by rotation so that it is a so-called fast-rotator galaxy (slow rotators fall inside or near the dashed box100). It is like other quiescent galaxies at high redshift (MRG sample, diamonds)19 and unlike local quiescent galaxies (SAMI sample, circles)33, including the most massive local quiescent galaxies (MASSIVE sample, squares)101. b, Mass versus size diagram, illustrating that GS-10578 is extremely compact. To join the z = 0 distribution, our galaxy must grow in size by a factor of 10. Our 1σ uncertainties were obtained by perturbing the measurements and bootstrapping 100 times.
