论文摘要
根据Pantheon Supernova数据的最近提出的模型无关分析，我们重新审视了立方加里龙模型的宇宙学动力学。在背景级别，它显示与数据兼容，而优先于标准的典型模型。此外，该模型被证明与跨普兰克的审查猜想（以及其他赃物猜想）一致。结果表明，对于给定的参数化，该模型无法满足从线性〜扰动级别从万神殿数据集得出的重建的生长指数的边界。
We revisit the cosmological dynamics of the cubic Galileon model in light of the recently proposed model-independent analyses of the Pantheon supernova data. At the background level, it is shown to be compatible with data and preferred over standard quintessence models. Furthermore, the model is shown to be consistent with the trans-Planckian censorship conjecture (as well as other Swampland conjectures). It is shown that for the given parametrization, the model fails to satisfy the bounds on the reconstructed growth index derived from the Pantheon data set at the level of linear~perturbations.
