用远距离Ia超新星数据的共形宇宙学模型参数：“金”和“银”
Conformal Cosmological Model Parameters with Distant SNe Ia Data: "gold" and "silver"
摘要：
假设Ia型超新星（SNe Ia）是标准的烛光，人们可以用它们来检验宇宙学理论。哈勃太空望远镜团队分析了186个超新星Ia \cite{Riess_04}，以测试与宇宙膨胀长度相关的标准宇宙学模型（SC）并评估其参数。用同一样本确定了具有相对参考单位的共形宇宙模型（CC）的参数，从而将广义相对论的共形量解释为观测量。我们的结论是，真正的测试是非常有用的，并允许评估模型的参数。从形式统计的角度来看，CC模型的最佳拟合与SC模型与$Ω_Λ=0.72, Ω_m=0.28$的最佳拟合几乎是相同质量的近似。如前所述，对于CC模型，刚性物质成分可以替代SC模型中存在的$Λ$项（或精华）。我们注意到，一个自由的无质量标量场可以产生这样的刚性物质。我们描述了我们的分析结果，为最近的“黄金”数据（192超新星Ia）。
英文摘要：
Assuming that supernovae type Ia (SNe Ia) are standard candles one could use them to test cosmological theories. The Hubble Space Telescope team analyzed 186 SNe Ia\cite{Riess_04} to test the Standard Cosmological model (SC) associated with expanded lengths in the Universe and evaluate its parameters. We use the same sample to determine parameters of Conformal Cosmological model (CC) with relative reference units of intervals, so that conformal quantities of General Relativity are interpreted as observables. We concluded, that really the test is extremely useful and allows to evaluate parameters of the model. From a formal statistical point of view the best fit of the CC model is almost the same quality approximation as the best fit of SC model with $Ω_Λ=0.72, Ω_m=0.28$. As it was noted earlier, for CC models, a rigid matter component could substitute the $Λ$-term (or quintessence) existing in the SC model. We note that a free massless scalar field can generate such a rigid matter. We describe results of our analysis for more recent "gold" data (for 192 SNe Ia).
