Is dark matter of large gallaxies supersymmetric to black holes?

This post is a reaction to recent NS article "Missing dark matter mystery in small galaxies". It's well known, large galaxies and galactic clusters are relatively abundant to dark matter with compare the smaller ones. This finding could have certain meaning in AWT cosmology, in which large gallaxies were formed by evaporation of central black holes, whereas smaller ones were formed rather by accretion (i.e. by classical mechanism with respect to contemporary cosmology). Another ideas presented in connection with this model  was dark star origin of gallaxies and the shielding effect of dark matter. This effect is understandable with respect to AWT mechanism, because of large content of antimatter considered in dark matter, which could have antigravity action at large distances. Presence of heavily ionized atom nuclei trapped makes dark matter detectable by X-ray telescopes, like Chandra.



It would mean, dark matter is in fact super-symmetric effect of black holes inside of galaxies. Without presence of central black holes the galaxies cannot contain material particles around it, because of no evaporation. This idea could have some meaning in holographic theory of Universe, too. This could explain both absence of dark matter outside, both black holes outside of small galaxies. 


But the whole subject is still quite speculative in this moment and additional observational data are required. Recently Hubble has found another evidence of dark matter presence near small galaxies. This study demonstrated, that the low-velocities of stars observed around dwarf galaxies are infact compatible with galaxy formation in dark-matter haloes. Stellar orbits in the outer regions of the resulting elliptical are very elongated, which can explain the observed velocities even in the presence of large amounts of dark matter.
