论文摘要
在本文中，我们探讨了相互作用的暗能量宇宙学的可能扩展，其中暗能和深色物质在彼此之间无与伦比的相互作用。特别是，我们专注于中微子部门，分析中微子肿块和有效中微子物种的影响。我们考虑了Planck 2018 Legacy Reakal数据以及其他几个宇宙学探针，在黑暗辐射部门没有发现新物理学的证据。因此，宇宙学的当前中微子约束应被视为坚固，因为一旦将所有可用的观察结果组合在一起，它们就不受深度依赖于黑暗扇区物理学。即，我们发现总中微子质量$m_ν<0.15 $ eV和许多有效的相对论自由度为$ n _ {\ rm eff} = 3.03^{+0.33} _ { - 0.33} _ { - 0.33} $，都在95 \％cl中，$ cos $ $ $ cosmology of $ cosmology of $ c cosm cosmology，对于相同的数据组合，$ n _ {\ rm eff} = 3.00^{+0.36} _ { - 0.35} $。
In this paper we explore possible extensions of Interacting Dark Energy cosmologies, where Dark Energy and Dark Matter interact non-gravitationally with one another. In particular, we focus on the neutrino sector, analyzing the effect of both neutrino masses and the effective number of neutrino species. We consider the Planck 2018 legacy release data combined with several other cosmological probes, finding no evidence for new physics in the dark radiation sector. The current neutrino constraints from cosmology should be therefore regarded as robust, as they are not strongly dependent on the dark sector physics, once all the available observations are combined. Namely, we find a total neutrino mass $M_ν<0.15$ eV and a number of effective relativistic degrees of freedom of $N_{\rm eff}=3.03^{+0.33}_{-0.33}$, both at 95\% CL, which are close to those obtained within the $Λ$CDM cosmology, $M_ν<0.12$ eV and $N_{\rm eff}=3.00^{+0.36}_{-0.35}$ for the same data combination.
