Kavli Affiliate: Joshua Frieman | First 5 Authors: Roman Scoccimarro, Joshua Frieman, , , | Summary: Using a diagrammatic approach to Eulerian perturbation theory, we analytically calculate the variance and skewness of the density and velocity divergence induced by gravitational evolution from Gaussian initial conditions, including corrections *beyond* leading order. Except for the power spectrum, […]
Kavli Affiliate: Wayne Hu | First 5 Authors: Wayne Hu, , , , | Summary: We develop and examine the principles governing the formation of distortions in the cosmic microwave background. Distortions in the frequency or spectral distribution of the background probe the thermal history of the universe whereas those in the angular temperature distribution […]
Kavli Affiliate: Anthony Zee | First 5 Authors: Anthony Zee, Edouard Brézin, , , | Summary: We prove that in random matrix theory there exists a universal relation between the one-point Green’s function $G$ and the connected two- point Green’s function $G_c$ given by vfill $ N^2 G_c(z,w) = {part^2 over part z part w} […]
