论文摘要
有了Pantheon的数据，我们可以使用超过一千个超新星IA的样本，覆盖了广泛的红移，精确精度。在这里，我们将其拟合到具有各种宇宙学模型的相应Hubble--Lema-图图，并具有伴随的灭绝，超新星的发光度的演变以及由于部分非化学因素而引起的红移组件。标准模型非常适合包含暗能量的数据，但是解决方案具有其他几个变量的变性。因此，不能单独使用SNE IA的Hubble-Lema-trete图来推断出深色能量加速膨胀方案的存在。 在此堕落中，可以很好地适合数据的模型包括以下替代解决方案：Einstein-灰色灭绝$ a_v = 1.2 \ times 10^{ - 4} $ mpc $^{ - 1} $;线性Hubble-LemaîtreLaw Law static Euclidean与灰色灭绝$ a_v = 0.4 \ times 10^{ - 4} $ mpc $^{ - 1} $;带有疲倦的光和灰色灭绝的静态欧几里得$ a_v = 2.8 \ times 10^{ - 4} $ mpc $^{ - 1} $; Einstein-与绝对幅度演化的保姆$α= -0.10 $ mag gyr $^{ - 1} $; $ω_m= 0.07-07-07 $，$ω_λ= 0 $和部分非物质的疲倦的红移/blueShift，带衰减/增强$ | k_i | k_i | <2.2 \ 2.2 \ times 10^{ - 4} $ mpc $^loculs loculs $ m $ m $ ingomp，
With data from Pantheon, we have at our disposal a sample of more than a thousand supernovae Ia covering a wide range of redshifts with good precision. Here we make fits to the corresponding Hubble--Lemaître diagram with various cosmological models, with intergalactic extinction, evolution of the luminosity of supernovae, and redshift components due to partially non-cosmological factors. The data are well fitted by the standard model to include dark energy, but there is a degeneracy of solutions with several other variables. Therefore, the Hubble--Lemaître diagram of SNe Ia cannot be used alone to infer the existence of the accelerated expansion scenario with dark energy. Within this degeneracy, models that give good fits to the data include the following alternative solutions: Einstein--de Sitter with gray extinction $a_V=1.2\times 10^{-4}$ Mpc$^{-1}$; linear Hubble--Lemaître law static Euclidean with gray extinction $a_V=0.4\times 10^{-4}$ Mpc$^{-1}$; Static Euclidean with tired light and gray extinction $a_V=2.8\times 10^{-4}$ Mpc$^{-1}$; Einstein--de Sitter with absolute magnitude evolution $α=-0.10$ mag Gyr$^{-1}$; Friedmann model with $Ω_M=0.07 - 0.29$, $Ω_Λ=0$ and partially non-cosmological tired-light redshifts/blueshift with attenuation/enhancement $|K_i|<2.2\times 10^{-4}$ Mpc$^{-1}$ (although requiring calibration of $M$ incompatible with local SNe measurements).
