Explanation, the central galaxy black hole attracts other stellar nurseries also electrical guided by the Birkeland currents system ( Q-FFF Theory), which are supposed to be formed by the new physics Galaxy Black Holes ( GABHs) ond even Stellar BHs (SABHs). Both types create an a-symmetric Birkeland current carousel with the central star or galaxy black hole. That is why only the central black hole is shrouded by plasma and even temporary black holes before merging.
How a new star is compressed by the Zero Point vacuum pump out of two Birkeland plasma streams produced by the Penrose =Q-FFF black Holes of the Herbig Haro system. See the white/grey hole location in the middle below with less negative charge.
