摘要

最近，宇宙学张力的出现使人们对ΛCDM模型的一致性产生了怀疑。为了在一致的宇宙学框架内约束中微子质量，我们研究了类轴子早期暗能量（Axi-EDE）和AdS-EDE模型中具有正常层次（NH）和倒层次（IH）的三种大质量中微子。我们使用了联合数据集，包括来自普朗克 2018 的宇宙微波背景功率谱、Ia 型超新星 Pantheon、重子声学振荡和来自 SH0ES 的数据。对于νAxi-EDE模型，我们得到了< 0.152 eV和< 0.178 eV，而对于νAdS-EDE模型，我们发现了< 0.135 eV和< 0.167 eV。我们的结果表明，νAxi-EDE 和 νAdS-EDE 模型都更倾向于 NH。

Cosmological constraints on neutrino mass within consistent cosmological models* * We acknowledge the use of HPC Cluster of ITP-CAS. XZ is supported by the National Natural Science Foundation of China (12005183). QGH is supported by the National Natural Science Foundation of China (12250010, 11975019, 11991052, 12047503), and the Key Research Program of Frontier Sciences, CAS, (ZDBS-LY-7009)

Recently, the emergence of cosmological tension has raised doubts about the consistency of the ΛCDM model. To constrain the neutrino mass within a consistent cosmological framework, we investigate three massive neutrinos with normal hierarchy (NH) and inverted hierarchy (IH) in both the axion-like early dark energy (Axi-EDE) and AdS-EDE models. We use joint datasets including the cosmic microwave background power spectrum from Planck 2018, Pantheon of type Ia supernova, baryon acoustic oscillation, and

data from SH0ES. For the νAxi-EDE model, we obtain

< 0.152 eV and

< 0.178 eV, whereas for the νAdS-EDE model, we find

< 0.135 eV and

< 0.167 eV. Our results exhibit a preference for NH in both the νAxi-EDE and νAdS-EDE models.
