Care to share a little more on the “disk” vs “torus” dynamic? I’ve got my own ideas about when we would get one versus the other (or how we would explain why both would appear), but I would like your input first.
There appears to be a scaling relationship present. Depending on the filtering techniques and viewing geometry both "disk" and "torus" can be present with either spiral and/or elliptical galaxy. Here is elliptical galaxy NGC4261
Here; spiral Galaxy NGC 1512
NGC4261 above is a LARGE scale CND torus
In the context of the plasma electrodynamics the ballistic “projectile” could correspond with the (tubular) filament of an electric current during an electric “arc” (arc mode and/or “spark-mode”). The "surface", or "wall" on the other hand could be the double-layer of any number of "
molecular clouds". Here is another example of an actual Plasma Torus using this same motif “created by a jet of water striking a crystal plate”:
Toroidal plasmoid generation via extreme hydrodynamic shear
One form of matter serving as a “projectile” intersecting another form of matter acting as a “wall” or surface produced “a stable ring of plasma in open air”, a Plasma Torus, in midair, at the lab. Although there is a “projectile” (the jet of water) and a surface (the crystal plate) what is missing? The Mini-Spiral - (Vortex). In this experiment that feature is not really missing though.
Comparatively, the full length of the Double Helix Nebula electric current filament as it connects to the bright Plasmoid Sag A*, then the CND Torus feature, then also the substances being drawn into the opening of the CND undergoing vortex motions (aka “Mini-Spiral”) notice Fig. 1 in the above doc and its caption.
Fig 1 panel ‘C’ shows streamers
“as they stretch radial from the impinging site…” . So these "streamers" would correspond to the arms a spiral galaxy but in the experiment they are going in the wrong direction - radially *from* the impinging site. So this would more so symbolize the radial nature of an elliptical configuration.
With regard to CND's the molecular clouds that interact with the ionizing torus are very important. Ionized or not, matter drawn into the filament channel (the MIni-Spiral), allows some portions of the DHN filament length to be detected.
So: Unlike the molecular clouds that have been detected interacting with the smaller scale CND/DHN/and its Mini-Spiral the potential of molecular clouds at the edges of the disk of spiral galaxies becoming "streamers" analogous to the inward propagating "arms of spiral galaxies remains (as far as I know) ... a thing not pondered in astrophysics?
Here is a schematic of the well documented activities of SgrA including a graphic for the Double Helix Nebula (DHN) filament:
Discovery of the Pigtail Molecular Cloud in the Galactic Center
Any number of images have been made of smaller filamentary matter heading INTO the CND vortex (Mini-Spiral). If this were scaled up to the size of The Milky Way, or NGC 4261, or NGC 1512 ... where are the corresponding molecular clouds at some distant outer edge of these galactic disk that would slowly become energized, and increasingly ionized, as they were likewise drawn inward? Meanwhile, simultaneously, the CND footprint of an electric current with its "laminar flow" as it penetrated into and/or interacted with the double-layer surface(s), or "wall", of molecular clouds might present a "torus" regardless of galaxy type.
It would be an interesting scaling relationship if VAST molecular clouds were to be found wafting around and/or elongated towards the far distant edges of galactic disk. Something along this line of thought.
