There are several observations implying the birkelund Z-pinch is involved in the ejection of a plasmoid.
First, for background:
EU has a description of a plasmoid and its creation.
The YouTube video is titled: "Wal Thornhill: Black Hole or Plasmoid? | Space News" from April 2019
At about 7:45 is the plasma focus description for creating a plasmoid. The jets from a plasmoid are also described but the jets are plasma and neutrons, not a plasmoid. A plasmoid apparently cannot create another plasmoid. Its creation is a different mechanism involving a plasma focus.
If an X-ray point source is separate out in space, the only possibility is a plasmoid. A star ejected from a galaxy would probably dissipate when lacking its electrical current from the galaxy. A plasmoid is an entity which can remain stable for some time. so it can sustain its synchrotron radiation.
Here is a collection of possible ejected plasmoids. These are 4 posts to EUT.
1) 09/26/2019 post: Plasmoids in a Spiral Galaxy Arms
Chandra took an image of galaxy SDSS J084905.51+111447.2 with X-ray point sources in its disturbed spiral arms.
The post's main article describes 3 sources. The post notes another story about this galaxy but that one identified 8 sources. X-ray intensity contours require an interpretation. The stories suggest a collision of galaxies but the post concludes the arms are just distorted for a single spiral galaxy.
2) 10/10/2019 post: M82 Galaxy Is Surrounded By X-Ray Sources
Chandra took an image of the star burst galaxy M82 which is surrounded by "hundreds" of X-ray point sources. M82 is probably an edge-on spiral but that angle results in its Irregular classification.
3) 10/14/2019 post: Toothbrush Cluster
The handle of the "toothbrush" is a twisted birkelund current pair with a bend near the handle's end.
The post mentions the story of an image taken by VLA:
Deep VLA Observations Of The Toothbrush Cluster
Below the "toothbrush" are 2 bright X-ray sources. Their location below the end of the "toothbrush" suggests a possible ejection. There is no other explanation for their location.
4) 1/12/2020 post: Arp, Quasars, M51
excerpt from the post: "A survey of the Whirlpool Galaxy revealed close to 500 X-ray sources."
Halton Arp observed the apparent ejection of quasars from a Seyfert galaxy. A Seyfert is a very active spiral galaxy, M51 is a Seyfert.
The 500 are probably not all quasars but some might be plasmoids.
The common theme for these 4 posts and X-ray sources is a birkelund current pair with a bend.
Every spiral galaxy has this combination with the bend resulting in the current filaments out the respective spiral arms.
Perhaps this combination can create a plasma focus resulting in the creation and ejection of a plasmoid.
Each observation in the 4 posts involved a more active arrangement than found in just a "typical" spiral galaxy. That is why plasmoids do not arise from every galaxy.
This post is only about plasmoids which appear to have been ejected. The process of how the plasmoid is ejected and then observed at some distance from the point of ejection is undefined. Only one step at a time is possible.
