摘要
本文基于Planck 857、545和353 GHz以及IRAS 100微米数据，提出了一个尘埃辐射的全天模型。通过对数据进行修正黑体拟合，我们给出了353-3000 GHz范围内尘埃光学深度、温度和谱指数的全天图。该模型在5角分尺度上紧密代表了数据。与广泛使用的Finkbeiner、Davis和Schlegel模型相比，它显示出约30%的变化。Planck数据使我们能够均匀地估计整个天空的尘埃温度，从而提供了比以往全天尘埃模型改进的尘埃光学深度估计，尤其是在高对比度分子区域。报告了从弥散到更稠密星际介质（ISM）中353 GHz尘埃不透明度的增加。这与观测到的尘埃温度的降低有关，这至少部分可归因于尘埃不透明度的增加。我们还报告了在HI柱密度低于时尘埃辐射的过量，这可能是暖电离介质中尘埃的标志。在高银纬的弥散ISM中，我们报告了与之间的反相关，而尘埃比光度（即每个氢原子积分频率的总尘埃辐射，即辐射亮度）大致保持恒定。这意味着在弥散的高纬度ISM中，作为尘埃柱密度示踪剂的可靠性不如我们在分子云中得出的结论，因为在分子云中，与通过恒星色余测量估计的尘埃消光之间的相关性很强。为了估计高纬度河外场中的银河系E(B-V)，我们开发了一种基于热尘埃辐射亮度（而非尘埃光学深度）的新方法，并使用斯隆数字巡天数据中类星体的红化测量将其校准到E(B-V)。
