Extended Data Fig. 4: Map of Brγ velocity dispersion.
From: Two separate outflows in the dual supermassive black hole system NGC 6240
The contours delineate the Brγ flux distribution and are set at 15%, 30%, 45%, 60%, 75% and 90% of the peak of emission. The dashed rectangle delimits the base of the Hα bubble. Regions in white correspond to pixels where the Brγ flux is less than 5% of the peak of emission and thus were masked out. North is up and east is to the left. The colour bar indicates the range of velocity dispersion values observed in units of kilometres per second.
