Darkon流体-宇宙暗区的模型?

Darkon fluid - a model for the dark sector of the Universe?

Peter C. Stichel, Wojtek J. Zakrzewski

摘要:

我们引入暗子作为伽利略无质量自引力流体的流体粒子。该流体表现出与$z=5/3$的各向异性缩放。最小引力耦合动态地产生任一符号的引力质量密度。因此,这种流体可以作为宇宙暗区的模型。它的宇宙学解给出了早期宇宙的减速阶段和晚期宇宙的加速阶段。定常流解是否会导致一个限制势,从而成为一个可能的晕模型?

英文摘要:

We introduce darkons as fluid particles of a Galilean massless self-gravitating fluid. This fluid exhibits anisotropic scaling with $z=5/3$. The minimal gravitational coupling dynamically generates a gravitational mass density of either sign. Hence such fluid may serve as a model for the dark sector of the Universe. Its cosmological solutions give a deceleration phase for the early Universe and an acceleration phase for the late Universe. Will the steady flow solutions lead to a confining potential and so a possible model for halos?
