论文摘要
已经提出了涉及暗物质与暗能量部门之间相互作用的模型，以减轻长期存在的哈勃持续持续张力。在本文中，我们分析使用模拟Planck数据时，这些相互作用模型获得的约束和潜在提示是否保持不变。有趣的是，我们的模拟表明，仅在处理当前的CMB Planck测量值时，可能会出现危险的虚假检测和暗能质之间的非零相互作用。针对未来的CMB观察结果进行了相同的假设，发现只有宇宙方差有限的极化实验，例如PICO或PRISM，才能破坏现有的参数退化性并提供可靠的宇宙学约束。本文强调了与在异国情调宇宙学场景中提取宇宙学限制时与模拟获得的数据分析产生的结果的极端重要性。
Models involving an interaction between the Dark Matter and the Dark Energy sectors have been proposed to alleviate the long standing Hubble constant tension. In this paper we analyze whether the constraints and potential hints obtained for these interacting models remain unchanged when using simulated Planck data. Interestingly, our simulations indicate that a dangerous fake detection for a non-zero interaction among the Dark Matter and the Dark Energy fluids could arise when dealing with current CMB Planck measurements alone. The very same hypothesis is tested against future CMB observations, finding that only cosmic variance limited polarization experiments, such as PICO or PRISM, could be able to break the existing parameter degeneracies and provide reliable cosmological constraints. This paper underlines the extreme importance of confronting the results arising from data analyses with those obtained with simulations when extracting cosmological limits within exotic cosmological scenarios.
