Fig. 4: Flux and kinematic maps of the [O iii] λλ4949,5007, Hα and [N ii] λλ6548,6583 nebular lines.
From: A fast-rotator post-starburst galaxy quenched by supermassive black-hole feedback at z = 3
a–c, Flux maps obtained by fitting one or two Gaussians to the emission lines (Methods) for [O iii] λλ4949,5007 (a), Hα (b) and [N ii] λλ6548,6583 (c). d–f, Non-parametric median velocities for [O iii] λλ4949,5007 (d), Hα (e) and [N ii] λλ6548,6583 (f). g–i, Interpercentile line widths for [O iii] λλ4949,5007 (g), Hα (h) and [N ii] λλ6548,6583 (i). j–l, 10th percentile velocity for [O iii] λλ4949,5007 (j), Hα (k) and [N ii] λλ6548,6583 (l). m–o, 90th percentile velocity for [O iii] λλ4949,5007 (m), Hα (n) and [N ii] λλ6548,6583 (o). For GS-10578 (whose continuum emission is highlighted by the red dashed ellipse), most of the emission is from a broad, blueshifted component. Together with information from the BPT diagram (Fig. 3), this is evidence for an AGN-powered outflow.
