“The physics that creates the jets remains a topic of research with a likely energy source being infalling matter swirling toward the central black hole.”
Yes, it’s one of those “issues” they have yet to resolve to get a purely gravity-based cosmological model to match up with observed phenomena. Here’s an alternative hypothesis:
The galaxy itself is a spinning disc of plasma, and any such moving mass of plasma will create a magnetic field. The magnetic field lines will run perpendicular to the direction of current flow, and in a spinning disc arrangement, the field produced should be a toroid, with the donut hole of the toroid located at the galactic center. In such an arrangement, the surrounding toroid field will exert a containment effect on the plasma, but this containment effect is going to be weakest in the area of the donut hole, making the superposition of spinning disc and toroid magnetic field an inherently “leaky” containment system.
The fact that the galactic center is also the densest part, and may also contain black holes, certainly should be a contributing factor to any plasma being ejected from the system, however to ignore the obvious electromagnetic effects which are pertinent is just foolish.
If you look at the photo, it could appear that the plasma jets are pouring out in a convex angle, with the galaxy in the forefront and the plasma jets bending away from us, rather that 180 degrees on each side of the galaxy.
