Spatial Variation of the Fine-Structure Parameter and the Cosmic Microwave Background
Kris Sigurdson, Andriy Kurylov, Marc Kamionkowski
We study the effects on cosmic microwave background (CMB) temperature and polarization anisotropies of spatial fluctuations of the fine-structure parameter between causally disconn…
