new Dark Matter (?)

Ever deepening endeavors continue to fully understand the cosmological Dark Matter. There have been new approaches to extrapolate its nature.

At Newcastle University, a team has tried for clarity in the Ultracold Bose Einstein condensates because of the fuzzy behavior viewed. It is postulated that physical state of the halo are the source and with gravitationally bound structures are influenced by the Bose-Einstein condensates, BEC.  The scientists say they determine that fuzzy halos may have a turbulent state and fluctuations which inhibit coherence. The center has a 'coherent solition core with a transition region'. This also distinguishes this model from the known cold dark matter. The researchers say this makes the fuzzy Dark Matter almost indistinguishable  from the BEC. They say that exploring with ultracold atomic physics could likewise open new ways of vistas on the natures in the universe. Ultracold meaning at zero Kelvin.

Their artlcle was published June 8, 2023 by Newcastle University and released to Monthly Notices of the Royal Astronomical Society. mnras/stad591.
