论文摘要
可以将相互作用的深色物质 - 漆黑能量（IDMDE）模型作为目前可能影响宇宙结构的挑战之一。在这项工作中，我们研究了IDMDE模型中综合的Sachs-Wolfe（ISW）效应。为此，我们最初为IDMDE模型引入了一个理论框架。此外，我们简要讨论了IDMDE模型的稳定性条件，并通过为能量密度传输速率指定简单的功能形式，我们计算扰动方程。在下文中，我们计算IDMDE模型的物质功率谱的幅度，并将其与从$λ$ CDM模型获得的相应结果进行比较。此外，我们计算IDMDE模型的Multiple Order L阶L的ISW自动功率频谱的幅度。结果表明，IDMDE模型中ISW自动功率频谱的振幅对于不同的幻影暗能量方程的行为与$λ$ CDM模型相似，而对于$λ$ CDM模型，状态的典型深色能量方程，对于ISW-Auto power power Spectrum的振幅，对于IDMDE的模型均应比一个$ $ $ $ $ cdm。同样，事实证明，耦合参数的不同值的相应结果表明，$ξ$与IDMDE模型中的ISW-Auto功率谱量成反比。最后，通过采用四个不同的调查，我们计算了ISW交叉功率谱的幅度作为IDMDE模型的多极订单$ L $的函数。结果表明，对于$ω_ {\ rm x} $的所有值，IDMDE模型的ISW交叉功率谱的幅度高于$λ$ CDM模型获得的幅度。同样，事实证明，IDMDE模型中ISW交叉功率谱的幅度与耦合参数$ξ$的值成反比。
Interacting dark matter-dark energy (IDMDE) models can be taken to account as one of the present challenges that may affect the cosmic structures. In this work, we study the integrated Sachs-Wolfe (ISW) effect in IDMDE models. To this end, we initially introduce a theoretical framework for IDMDE models. Moreover, we briefly discuss the stability conditions of IDMDE models and by specifying a simple functional form for the energy density transfer rate, we calculate the perturbation equations. In the following, we calculate the amplitude of the matter power spectrum for the IDMDE model and compare it with the corresponding result obtained from the $Λ$CDM model. Furthermore, we calculate the amplitude of the ISW auto-power spectrum as a function of multipole order l for the IDMDE model. The results indicate that the amplitude of the ISW auto-power spectrum in the IDMDE model for different phantom dark energy equations of state behaves similar to the one for the $Λ$CDM model, whereas, for the quintessence dark energy equations of state, the amplitude of the ISW-auto power spectrum for the IDMDE model should be higher than the one for the $Λ$CDM model. Also, it turns out that the corresponding results by different values of the coupling parameter demonstrate that $ξ$ is inversely proportional to the amplitude of the ISW-auto power spectrum in the IDMDE model. Finally, by employing four different surveys, we calculate the amplitude of the ISW-cross power spectrum as a function of multipole order $l$ for the IDMDE model. The results exhibit that the amplitude of the ISW-cross power spectrum for the IDMDE model for all values of $ω_{\rm x}$ is higher than the one obtained for the $Λ$CDM model. Also, it turns out that the amplitude of the ISW-cross power spectrum in the IDMDE model changes inversely with the value of coupling parameter $ξ$.
