M77: Just a good example of how multiple dual Herbig Haro (HH) black holes (BHs) seem to be forced magnetically to align parallel with the original dual large Mother black holes, (A) meeting in the middle leaving a bar (B) behind. (changing function into dual HH jet related bowshocks or: Galaxy Anchor Black Holes, perpendicular to the galaxy disc. according to Q-FFF Theory.) Each filament should represent the original dual jets between these HH BHs. (Q-FFF Theory)
The small multiple secondary HH black holes are assumed to be produced by Supernova starspot micro black holes ( see second image)
