A representation of overdensity structure in the Graziani et al. (2019) model of peculiar velocities inferred from Cosmicflows-3 distances restricted to the supergalactic coordinate range −13,000 < SGY < 0 km s⁻¹. Isocontours from gray to red are at density contrasts of δ = 0.8, 1.3, and 1.8. In this and following figures, red, green, and blue arrows emanating from the origin are 5000 km s⁻¹ in length along the positive SGX, SGY, and SGZ axes, respectively. The view is looking in from negative SGY. Important features are labeled.
