The South Pole Wall in the Hoffman et al. model3D Model
A representation of overdensity structure in the Hoffman et al. (2020) model of peculiar velocities inferred from Cosmicflows-3 distances restricted to the supergalactic coordinate range -6,000 < SGY < -3,000 km/s. The following levels are visualized: delta=0 in grey, delta=0.5, 1.0, 1.5 in nuances of red. For comparison, the South Pole Wall as reconstructed using the Graziani et al (2019) model is superimposed as a black wireframe isosurface.
The red, green, blue arrows emanating from the origin are 5,000 km/s in length along the positive SGX, SGY, SGZ axes of the Supergalactic Coordinate System, respectively.
This interactive visualization has been produced as part of the following paper: “Cosmicflows-3: The South Pole Wall” by Daniel Pomarède, R. Brent Tully, Romain Graziani, Hélène Courtois, and Jérémy Lezmy, The Astrophysical Journal 897 (2020) 133.
