Similar star forming rings follow deeper and deeper inside the nucleus of the galaxy. In the end a luminous torus forms which illumines the core from where quasar like objects are ejected. A dark spiral sits at the darker spot surrounded by the luminous torus. This dark spiral pours out gases from the centre which heats up and creates the observed x-ray and optical luminosity.

Spiral arms are in the process of forming rings while ejections occur from two opposite ends of the bar axis at the centre. True centre of the galaxy is a dark spot (dark spiral) which is seen to eject a luminous quasar. The structure at galactic centre mirrors the structure at larger scales.

What one observes in the scale of thousands of light years is reflected in the structure seen at the nuclei in the scale of light years.It seems generic in all galaxies in the universe. The activities in larger scale also mirror the activities at the nuclear scale.

This galaxy has been studied in connection with ejections of quasars from its centre. It has unusual density of quasars in it surrounding. The structure formed of quasars at the heart of this galaxy reflects its shape in the scale of 100 thousand light years.
