# The variance of the CMB temperature gradient: a new signature of a multiply connected Universe

@article{Aurich2021TheVO, title={The variance of the CMB temperature gradient: a new signature of a multiply connected Universe}, author={Ralf Aurich and Thomas Buchert and Martin J. France and Frank Steiner}, journal={Classical and Quantum Gravity}, year={2021}, volume={38} }

In this work we investigate the standard deviation of the cosmic microwave background (CMB) temperature gradient field as a signature for a multiply connected nature of the Universe. CMB simulations of a spatially infinite Universe model within the paradigm of the standard cosmological model present non-zero two-point correlations at any angular scale. This is in contradiction with the extreme suppression of correlations at scales above 60° in the observed CMB maps. Universe models with… Expand
