Neural network reconstruction of density and velocity fields from the 2MASS Redshift Survey

Robert Lilow, Punyakoti Ganeshaiah Veena, Adi Nusser

We reconstruct the 3D matter density and peculiar velocity fields in the local Universe up to a distance of 200$h^{-1}$Mpc from the Two-Micron All-Sky Redshift Survey (2MRS), u…
