论文摘要
我们使用$ h（z）$测量结果对一致性模型进行无效测试，以模仿下一代调查，例如欧几里得和SKA。为此，我们部署了一种非参数方法，因此我们对基准宇宙学和统计分析做出最小的假设。我们产生模拟假设不同的宇宙学模型，以验证我们可以如何区分它们的签名。我们发现，SKA和类似欧几里得的调查应该能够彻底区分与Planck CMB数据兼容的一致性和替代性暗能量模型。我们得出的结论是，如果基准模型之一代表真正的宇宙，那么SKA和Euclid将能够以具有统计学意义的方式伪造一致性模型，而无需对基础宇宙学的假设做出假设。
We perform null tests of the concordance model, using $H(z)$ measurements that mimic next-generation surveys such as Euclid and the SKA. To this end, we deploy a non-parametric method, so that we make minimal assumptions about the fiducial cosmology as well as the statistical analysis. We produce simulations assuming different cosmological models in order to verify how well we can distinguish between their signatures. We find that SKA- and Euclid-like surveys should be able to discriminate sharply between the concordance and alternative dark energy models that are compatible with the Planck CMB data. We conclude that SKA and Euclid will be able to falsify the concordance model in a statistically significant way, if one of the benchmarks models represents the true Universe, without making assumptions about the underlying cosmology.
