Abstract
One of the basic assumptions used in the study or the dark matter in clusters or galaxies (essentially any nonluminous mAss source: massive neutrinos, axions, blackholes, bricks) is that this matter has a distribution similar to the galaxies–galaxies are “good” tracers or the dark matter. Unfortunately, when using galaxies, determination of the distribution of the dark matter in the cores or the cluster is very uncertain.
