2015年CMB观测情况

Status of CMB observations in 2015

Martin Bucher

摘要:

2.725 K的宇宙微波背景在现代宇宙学的发展中发挥了关键作用,它为限制在非常大的红移下发生了什么的可能理论和几乎可以追溯到大爆炸初始奇点的理论推测提供了坚实的观测基础。在讲述了该领域一些鲜为人知的历史后,我总结了当前的观测情况,并讨论了未来的一些令人兴奋的挑战:B模式的寻找、宇宙微波背景辐射引力透镜势的精确映射以及超精确的特征描述宇宙微波背景辐射的频谱,这将允许利用频谱失真来探索新的物理学。

英文摘要:

The 2.725 K cosmic microwave background has played a key role in the development of modern cosmology by providing a solid observational foundation for constraining possible theories of what happened at very large redshifts and theoretical speculation reaching back almost to the would-be big bang initial singularity. After recounting some of the lesser known history of this area, I summarize the current observational situation and also discuss some exciting challenges that lie ahead: the search for B modes, the precision mapping of the CMB gravitational lensing potential, and the ultra-precise characterization of the CMB frequency spectrum, which would allow the exploitation of spectral distortions to probe new physics.
