Quasi-linear construction of the density field3D Model
Quasi-linear construction of the density field of the Cosmicflows-2 catalog of peculiar velocities.
Six levels of density are shown as isosurfaces of different colors, with density=1.3 in grey, and density= 1.7, 2.0, 2.3, 2.7, 3.0 in nuances of red.
The central signpost located at the origin of Supergalactic Coordinate System has 50 Mpc/h-long arrows pointing to the SGX (red), SGY (green), SGZ (blue) directions.
Annotations indicate major overdensities: 1: Virgo 2: Great attractor 3: Norma-Pavo-Indus 4: Arch 5: Perseus-Pisces 6: Coma 7: Hercules 8: Shapley 9: Lepus 10: Arrowhead
