标题： WOMBAT & FORECAST: Making Realistic Maps of the Microwave Sky

摘要： 基于波长的微波背景分析团队（WOMBAT）正在构建比之前模拟更逼真的微波图。 我们的前景模型代表了显著的改进：对于给定前景，当存在空间模板时，我们在天空的每个位置预测该成分的流量和光谱指数并估计不确定性。 我们将生成包含模拟宇宙微波背景各向异性与预期前景的图。 这些模拟图将作为WOMBAT挑战提供给社区，因此不了解其输入值的科学家可以对这些图进行分析以提取宇宙学参数。 这将测试前景减除、功率谱分析和参数估计技术的有效性，并有助于确定最需要进步的领域。 这些图也是FORECAST项目的一部分，该项目允许通过网络访问已知的前景图，以便规划宇宙微波背景任务。 显示英文摘要

摘要： The Wavelength-Oriented Microwave Background Analysis Team (WOMBAT) is constructing microwave maps which will be more realistic than previous simulations. Our foreground models represent a considerable improvement: where spatial templates are available for a given foreground, we predict the flux and spectral index of that component at each place on the sky and estimate uncertainties. We will produce maps containing simulated CMB anisotropy combined with expected foregrounds. The simulated maps will be provided to the community as the WOMBAT Challenge, so such maps can be analyzed to extract cosmological parameters by scientists who are unaware of their input values. This will test the efficacy of foreground subtraction, power spectrum analysis, and parameter estimation techniques and help identify the areas most in need of progress. These maps are also part of the FORECAST project, which allows web-based access to the known foreground maps for the planning of CMB missions.
