Abstract

Observational evidence consistently shows that the universe is spatially flat and undergoes Lorentzian time dilation as a function of redshift. In combination, such discoveries suggest that a Minkowskian description of cosmology might be technically viable. The thermal evolution that transpires in a conformal spacetime is herein derived. The description is constrained by the energy conservation of a unified cosmic fluid. The resulting model puts forth a Lorentzian correction for the temperature of the CMB as a function of redshift, which improves current data fitting without adding any free parameter. Furthermore, it sheds light upon the early galaxy formation problem: our model predicts up to 0.86 Gyr older objects within the first two billion years of the structure evolution in the universe.

对 CMB 温度演变的洛伦兹修正
观测证据一致表明,宇宙在空间上是平坦的,并随着红移的变化而发生洛伦兹时间膨胀。综合这些发现,明科夫斯基宇宙学描述在技术上可能是可行的。本文推导了共形时空中的热演化。这种描述受到统一宇宙流体能量守恒的约束。由此得出的模型为红移函数的 CMB 温度提出了一个洛伦兹修正,在不增加任何自由参数的情况下改进了当前的数据拟合。此外,它还揭示了早期星系形成的问题:我们的模型预测在宇宙结构演化的最初 20 亿年内,会出现多达 0.86 亿年的老天体。

期刊介绍: Astrophysics (Ap) is a peer-reviewed scientific journal which publishes research in theoretical and observational astrophysics. Founded by V.A.Ambartsumian in 1965 Astrophysics is one of the international astronomy journals. The journal covers space astrophysics, stellar and galactic evolution, solar physics, stellar and planetary atmospheres, interstellar matter. Additional subjects include chemical composition and internal structure of stars, quasars and pulsars, developments in modern cosmology and radiative transfer.
