"Are there other similar forms at macro scales, say in galactic lobes and nodes..."

That is a great question and the answer is yes:

"Scientists have discovered gigantic structures 25,000 light-years tall ballooning above and below the Milky Way. Within each curved lobe, extremely energetic electrons of unknown origin interact with lower-energy light to generate the gamma rays that define these bubbles."

At the atomic scale, the lobes are where energetic electrons are be found (electrons not in their ground state). At the galactic scale, we find energetic electrons in the lobes. I don't think this is a coincidence.
