Both equal sized Herbig Haro Black Holes are expanded by two "Tadpole Jets" creating a star or even galaxy in the middle, also called Polar Anchor Black Holes of stars or even galaxies.
String Nucleus Black Holes are assumed to be compacted by the oscillating Dark Energy Axion vacuum assumed to be one part of our Quantum Gravity on earth.
DEAD Galaxies: eaten and distributed by the jets, of its own Super massive Black Hole. However, Q-FFF Theory says:
Galaxy Black Holes, are the creators of the oscillating dark energy vacuum by the evaporation of the splitted central Big Bang Black holes, and the plasma discs aournd the center.
The Galaxy jets are the main distributors of new plasma created out of the Axion vacuum at each "Trapped Space Black Hole Horizon". already mentioned by Roger Penrose. and interpreted by Q-FFF Theory, as vacuum particle collider , creating charged plasma out of the vacuum in disc shape around the new black hole trapped space Horizon. However the big bang splitted unstable self accelerating Big Bang Tadpoles black holes seem to evaporate its nucleus into new Axion vacuum

A Hubble Space Telescope visible-light image of the galaxy MCG-03-34-064. Hubble’s sharp view reveals three distinct bright spots embedded in a white ellipse at the galaxy’s center (expanded in an inset image at upper right). Two of these bright spots are the source of strong X-ray emission, a telltale sign that they are supermassive black holes. The black holes shine brightly because they are converting infalling matter into energy, and blaze across space as active galactic nuclei. Their separation is about 300 light-years. The third spot is a blob of bright gas. The blue streak pointing to the 5 o’clock position may be a jet fired from one of the black holes. The black hole pair is a result of a merger between two galaxies that will eventually collide. Credit: NASA, ESA, Anna Trindade Falcão (CfA), Joseph DePasquale (STScI)
