Formation and breakdown of knots : Critical balance between equilibrium and non-equilibrium
...The kinematics of the galaxies are much more complex than simple rotation of the arms around a centre. They are not differential rotations in one direction. The rotational behaviour is coupled with spiral movement towards the centre, as well as they are intricately linked with the ejections from inside. The paths of inflow and outflow are non-rotational and they are complexly intertwined with the overall rotating structure. The motions in the very centre is even more complex. There the motions follow knot structures. These knots are, in fact, fractal knots, which means the knots at a particular scale embed a similar knots in its centre in the next descending scale. The central knot works as a structure with several outpouring mouths. The ejected streams from these mouths join the inflowing streams which then spiral towards the centre and give rise to the complex forms.
The knot formation inside the vortex eye follows the formation of the eye-walls, within which the space remains more empty. As the vortex intensifies, meso-vortices develop in this empty region. When three such meso-vortices appear inside the eye of the vortex they create the shape of a three-armed spiral at the centre. In the centre of such a spiral, one can discover a similar spiral of smaller size. In the heart of that smaller spiral one may find an even smaller spiral structure again.
This will continue until the formation of a 3D knot structure, which is so tightly bound that no more tightening can be done. At such a critical point the knot will collapse and outpouring will occur from the very heart of the structure. This outpouring will then be halted by the formation of the knot once again. This knot may again break and create outpouring. This will generate a phenomenon of occasional outpouring of matter from the centre.
...One can observe the ejections of structures from the centres of galaxies
and the centres of the clusters of galaxies when the central knot starts
breaking down. In this chapter I shall give examples of the famous seyfert
galaxy Ngc 1068 and the activities at the center of the Perseus cluster. Many
quasars are seen to be ejected from the center of the Ngc 1068. The situations
inside the centre of the Perseus cluster appear to be equally dramatic. The
galaxy at the centre of the Perseus cluster is known as Ngc 1275, or Perseus A.
This central region is well studied in x-rays too. In the framework of the
big-bang cosmology, it is believed that the activities at the centres of Ngc
1068 and the centre of Perseus A are driven by the presence of massive
black-holes. The activities in the centre are mostly explosive ejections causing
emissions of high-energy x-rays.
