Narrow Line Region


This animation rotates the narrow line region (NLR) to show you the cone-shaped region of illuminated clouds, then tips the quasar over to demonstrate that the illumination is coming from the intense nucleus of the quasar. Illuminated cones like this have been imaged in many nearby quasars. The existence of light-cones supports arguments for a doughnut-shaped torus within the NLR which directs the light in this way.
