标题： Satellite design parameters for detecting coherence in the microwave sky

摘要： 近年来人们认识到，宇宙微波背景（CMB）涨落的观测可以揭示早期扰动所表现出的相干程度的非常有趣的信息。 这一事实应该允许足够详细的观测来清楚地区分几种竞争的结构形成模型。 我们研究了卫星解决相干性问题所需的任务参数。 我们的结果强调了小光束宽度的重要性，并支持PSI、FIRE和COBRAS/SAMBA卫星提案（按分辨率能力递增顺序）的情况。 第四项提案MAP的设计参数尚未公开。 显示英文摘要

摘要： Recently it has been realized that observations of fluctuations in the cosmic microwave background (CMB) can reveal very interesting information about the degree of coherence exhibited by the perturbations at early times. This fact should allow sufficiently detailed observations to clearly differentiate among several competing models of structure formation. We study the mission parameters required for a satellite to address the issue of coherence. Our results emphasize the importance of a small beamwidth, and support the cases for the PSI, FIRE and COBRAS/SAMBA satellite proposals (in increasing order of resolving power). Design parameters for a fourth proposal, MAP, have not been made available.
