Observations with the {\it James Webb Space Telescope} have revealed a high abundance of bright galaxies at redshift, $z\gtrsim 12$, which has been widely interpreted as conflicting with the $Λ$CDM model. In Cowley et al. (2018) predictions were made -- prior to the {\it JWST} observations -- for the expected abundance of these galaxies using the Durham semi-analytic galaxy formation model, {\sc galform}, which is known to produce a realistic population of galaxies at lower redshifts including the present day. Key to this model is the assumption of a ``top-heavy" initial mass function of stars formed in bursts (required to explain the number counts and redshift distribution of sub-millimetre galaxies). Here, we compare the rest-frame ultraviolet luminosity functions derived from {\it JWST} observations with those predicted by the Cowley et al. model up to $z=14$ and make further predictions for $z=16$. We find that below $z\sim 10$, the Cowley et al. predictions agree very well with observations, while agreement at $z\gtrsim12$ requires extending the model to take into account the timescale for the growth of obscuring dust grains at these very early times and its dependence on gas metallicity. We trace the evolution of these galaxies from $z=14$ to $z=0$ and find that their descendants typically reside in halos with a median mass $2.5\times 10^{13}\,h^{-1}\,\mathrm{M_{\odot}}$. The stellar masses of the descendants range from $3.2\times 10^{6}\,h^{-1}\,\mathrm{M_{\odot}}$ to $3.2\times 10^{11}\,h^{-1}\,\mathrm{M_{\odot}}$. Although these galaxies were all central galaxies at $z=14$, over half of their descendants end up as satellites in massive halos.

Abundance matching for low mass galaxies in the CDM and FDM models
星系和晕之间的近似匹配已被证明是一种信息技术，比其他一些方法更少依赖于详细的物理近似。我们将讨论扩展到矮星系领域，并研究了另一种假设，即暗物质是由超轻粒子：模糊暗物质。我们发现，根据目前的观察，CDM和FDM都有困难的矮系统在本地组，但是，如果提出的机制，以减轻这些困难，他们从根本上不同的预测FDM和CDM在高红移。这些差异应允许明确的观测测试与目前计划的实验，与星系数量每单位体积的恒星质量超过$10^6$ M $_{\odot}$低FDM的因素（$10^{-2.7},10^{-2.0},10^{-1.7},10^{-0.7},10^{-0.1}$）在$z=(10,8,6,4,2)$。

Constraints on dark energy from the abundance of massive galaxies
这篇会议论文简要总结了Menci et al.（2020）和Menci et al.（2022）对动态暗能量模型的约束。动力学暗能量（DDE）模型已被提出来解决标准$Λ$冷暗物质（$Λ$ CDM）场景中出现的几个观测紧张局势。不同的DDE模型，参数化的状态方程参数$w_0$和它的时间导数$w_a$的本地值的不同组合，预测不同的大质量星系在早期宇宙的最大丰度。我们利用观测到的z>=4.5的大质量星系的丰度来约束DDE模型。为此，我们考虑了四个独立的探测：（i）CANDELS巡天在z~6观测到的恒星质量函数，（ii）由z~5观测到的亚毫米级大质量恒星形成星系估算的质量晕体密度，（iii）SPT巡天在z~7观测到的最大质量星系的稀有性，（iv）由观测到的质量晕体密度。（iv）从JWST早期观测中推断的z~10处大质量（M>10^10.5 Msun）星系的丰度。我们的探针排除了DDE参数空间的主要部分，这是允许由其他现有的探针。特别是，早期的JWST结果，如果得到证实，在2 $σ$置信水平下，与标准$Λ$ CDM情景存在紧张关系。
