摘要：
我们对基本的以太林关系（宇宙距离二元关系）进行了测试，该关系将视亮度距离D_L和角直径距离D_A联系起来，用于引力度规理论。我们利用DESI-DR2最新的角直径距离测量（按红移函数）以及多种Ia型超新星编目的视亮度距离进行分析。我们的结果表明，这些测量在统计上与以太林关系一致。除了确认以太林关系的底层假设（引力度规性、洛伦兹不变性和光子数守恒），我们的结果还对任何残余系统误差进行了严格检验。我们解释了没有发现偏离该关系的证据，从而将Ia型超新星绝对光度的演化约束为dM/dz=0.07±0.07，超过已计入Ia型超新星分析中的系统误差。我们讨论了如何利用以太林关系来约束动态暗能量分析中的系统参数，以提高几何探测的鲁棒性，使其更抗系统误差。
英文摘要：
We carry out a test of the fundamental Etherington relation (cosmic distance duality relation) which relates the luminosity distance $D_{\rm L}$ and angular diameter distance $D_{\rm A}$ in metric theories of gravity. We use the latest measurements of the angular diameter distance as a function of redshift from the Dark Energy Spectroscopic Instrument Data Release 2 (DESI-DR2) and the luminosity distance from a variety of compilations of Supernovae of Type Ia (SNeIa). Our results indicate that these measurements are statistically consistent with the Etherington relation. In addition to providing a confirmation of the underlying assumptions of the Etherington relation, i.e., the metric nature of gravity, Lorentz invariance and photon number conservation, our results are also a stringent test of any residual systematic effects. We interpret the absence of evidence of any deviation from this relation to constrain the evolution of the absolute magnitude of SNeIa to $dM/dz = 0.07 \pm 0.07$ over and above the systematics that are already accounted for in the SNeIa analyses. We discuss how the Etherington relation can be used to constrain systematic parameters in the analyses of dynamical dark energy using geometric probes, to make it more robust against systematic effects.
