Conclusion according to the Q-FFF Theory: the GABH (Galaxy Anchor Black Hole- and the resulting jet-Sructure) of M87, is more simple (more linear) than most Galaxies have.
The Milky Way and Andromeda seem to show a more complex jet structure and resulting Fermi bubble structure.

Q-FFF says: The more simple vacuum structure around the central jets of a galaxy, could be related to the increase of Super Nova explosions and most star formation at te end of the jet..
