Gravity in the Local Universe : density and velocity fields using CosmicFlows-4 by H. M. Courtois et al. on Wednesday 30 November

This article publicly releases three-dimensional reconstructions of the local

Universe gravitational field below z=0.8 that were computed using the full

catalogue CosmicFlows-4 of 56,000 galaxy distances and its sub-sample of 1,008

type Ia supernovae distances. The article also provides some first CF4

measurements of the growth rate of structure using the pairwise correlation of

peculiar velocities fsigma8 = 0.44(+/-0.01) and of the bulk flow in the Local

Universe of 200+/-88 kms-1 at distance 300 h-1Mpc.
