标题： Phantom crossing dark energy in Horndeski's theory

摘要： $\Lambda$CDM模型是一个非常成功的模型，它与宇宙微波背景辐射（CMB）、重子声学振荡（BAO）和宇宙大尺度结构的观测结果一致。 然而，最近指出了局部观测与PLANCK对CMB的观测中$H_0$值之间的差异。 缓解这种差异的一种方法是引入幻影暗能量，而不是宇宙学常数。 然而，幻影暗能量通常会遭受不稳定性。 我们将研究一种通用解，以克服幻影暗能量的困难，并构建一些具有幻影穿越的特定模型，这些模型可以与观测结果一致。 显示英文摘要

摘要： The $\Lambda$CDM model is a remarkably successful model which is consistent with the observations of cosmic microwave background radiation (CMB), baryon acoustic oscillation (BAO), and large scale structure of the Universe. However, the discrepancy in the value of $H_0$ between the local observations and PLANCK observation of CMB was recently pointed out. One of the way to ease the discrepancy is to introduce phantom dark energy instead of the cosmological constant. While, phantom dark energy often suffer from the instabilities. We will investigate the general solution to overcome the difficulty of phantom dark energy and construct some particular models which have a phantom crossing and can be consistent with the observations.
