Is Dark Matter a Bose-Einstein Condensate?

As the Ikerbasque researcher [Tom Broadhurst] explained, guided by the initial simulations of the formation of galaxies in this context, we have reinterpreted cold dark matter as a Bose-Einstein condensate. So, the ultra-light bosons forming the condensate share the same quantum wave function, so disturbance patterns are formed on astronomic scales in the form of large-scale waves.

 

This theory can be used to suggest that all the galaxies in this context should have at their center large stationary waves of dark matter called solitons, which would explain the puzzling cores observed in common dwarf galaxies.

The research also makes it possible to predict that galaxies are formed relatively late in this context in comparison with the interpretation of standard particles of cold dark matter. The team is comparing these new predictions with observations by the Hubble space telescope.

 

The results are very promising as they open up the possibility that dark matter could be regarded as a very cold quantum fluid that governs the formation of the structure across the whole Universe. This research opened up fresh possibilities to conduct research into the first galaxies to emerge after the Big Bang.

First I've heard of this idea for dark matter and energy. It sounds promising.

unfortunately its rather lacking in my opinion of numerous details I would have expected, for one thing he is describing an new form of dark matter called wave dark matter. Instead of cold dark matter of the LCDM model. The paper shows some interesting simulations done by other research, however lacks any details on the FLRW metrics, nor does it even use any thermodynamic formulas or particle physics references. The paper also does not specify which particle physics model he uses. SU(3), SO(10) etc?, nor does it even apply any perturbation metrics

 

For those lacks of details I would say its an interesting idea but does nothing to identify what dark matter would be, instead the article merely describes a possible type of influence. Though lacking in detail.

 

There is numerous models of how dark matter may be involved in early large scale structure formation by causing early anisotropies. If this paper wishes to compete with those papers already present its going to need considerable more detail.

 

The last proposal for what dark matter may be is relic neutrinos (right hand neutrinos=anti neutrino), including a possible direct measurement paper.

as far as dark Energy the SO(10) Higg's seesaw Mexican hat potential shows some promise, The SO(10) model delves extensively into the Higg's high energy metastability (further TEV physics studies at the LHC is underway to explore this possibility

 

 

The Standard Model Higgs boson as the inflaton (I particularly like this paper as it covers both inflation and the cosmological constant as one and the same, without including an exotic particle)

the above approaches from my studies of Cosmology and the numerous articles I've read seem to me to be the most promising approaches to the 3 questions in cosmology

inflation

dark energy

dark matter

 

What I particularly find impressive it the SO(10), has the potential of explaining all 3 problems, The arena of what is oft called "New physics" (TEV high energy research is impressive,)(one can only hope were on the edge of finally answering those 3 questions)
