论文摘要
詹姆斯·韦伯（James Webb）太空望远镜最近观察到了高红移的几个明亮而庞大的星系候选人。如此早期的大型星系似乎很难与标准的$λ$冷暗物质模型预测和解。我们讨论在哪些情况下，可以通过在宇宙学扰动的初始条件下引入原始的非高斯性来解释这种观察到的大量星系候选者。
Several bright and massive galaxy candidates at high redshifts have been recently observed by the James Webb Space Telescope. Such early massive galaxies seem difficult to reconcile with standard $Λ$ Cold Dark Matter model predictions. We discuss under which circumstances such observed massive galaxy candidates can be explained by introducing primordial non-Gaussianity in the initial conditions of the cosmological perturbations.
