The Noisy Universe
Gabriela Barenboim, Aurora Ireland, Albert Stebbins
We present observational constraints on large-scale white noise (LSWN) in the cosmic density field, a phenomenon predicted to arise from non-linear mode coupling during cosmologica…

Large Scale White Noise and Cosmology
Gabriela Barenboim, Aurora Ireland, Albert Stebbins
The generation of white noise on large scales is a generic property of the dynamics of physical systems described by local non-linear partial differential equations. Non-linearitie…
