Scalar Field Dark Matter in Clusters of Galaxies

The scalar field dark matter is just another step of mainstream physics toward model of dark matter based on scalar waves of Nicola Tesla (the existence of which the mainstream physics denies obstinately). I'm pretty sure, that at the very end the physicists realize, that what they're ignoring if not denying so long time is actually what they're looking for at the same moment. These scalar waves are similar to ripples at the water surface: they consist of many turbulences and fluctuations rather than of well defined particles and no ripple there is the same.

The scalar field model is most close to axions, which are assumed to be a solitons of the scalar field. But the mainstream physics adheres on defined particle models - it still cannot imagine the particles, which are different each other. But the observations of dark matter indicate, that it's actually composed of many constituents without well defined properties. The study above linked therefore proposed, that the dark matter is formed with lightweight particles, which gain additional energy by their excitations and these excited states provide the necessary variability for dark matter. These excited states are common in high energy physics of quark gluon plasma, yet they doesn't require unparticle model and solely new physics, for which the physicists still have no formal models developed yet.

From this reason it's not probably correct dark matter model - but at least it's getting closer. It's way better than so-called WIMPs model inspired by supersymmetry, which suggests the existence of massive, yet completely inert particles, which were never observed. If the hydrino exists, then it would be much closer to WIMPs rather than axions or scalar matter, because the mass of hydrino is close to mass of protons. The axions are very lightweight particles, even lighter than notoriously elusive neutrinos.
