论文摘要
我们平均使用Lemaitre-Tolman-Bondi(LTB)解决方案来描述物质分布的问题。在这里,我们研究了具有分形维度和量表过渡的本地宇宙的分形结构,从而确保了均匀的爆炸时间功能。我们使用最新类型的IA Supernova数据,万神殿汇编测试了我们的模型,并讨论了问题和可能的改进,得出结论,LTB宇宙学中的分形过渡不能用于解释黑暗能量的效果而不需要不均匀的大爆炸,但是在低尺度上研究结构可能是有用的。
We revisited the problem of describing, on average, a fractal distribution of matter using a Lemaitre-Tolman-Bondi (LTB) solution. Here we study the fractal structure of our local universe having a fractal dimension and a scale transition, ensuring an homogeneous bang-time function. We test our model with the latest type Ia supernova data, the Pantheon compilation, and discuss problems and possible improvements for it, concluding that a fractal transition in LTB cosmology cannot be used to explain the effects of dark energy without requiring an inhomogeneous big-bang, but it can be useful to study structures at low scales.
