Slice through the centre of the 2M++ galaxy survey with all voids intersecting it as identified by AVISM when applied to the McAlpine et al. (2025) (non-linear) and Carrick et al. (2015) (linear) density and velocity reconstructions. We use the supergalactic coordinate system (SGX, SGY, and SGZ) defined by De Vaucouleurs et al. (1991). The slice is ≈8 Mpc deep and contains the supergalactic plane (SGZ = 0). The void-finding procedure was restricted to the inner R ≤ 200/h Mpc in both cases. Near cosmological structures are highlighted with capital letters: the Virgo (V), Hydra-Centaurus (H), Norma (N), Shapley (S), and Perseus (P) clusters together with the Sculptor (S), Hercules (H), and Boötes (B) voids (Tully et al. 2019). Voids from the linear catalogue matching that from the non-linear with DSC coefficients larger (smaller) than 0.4 are displayed using the same colour and continuous (dotted) lines. The grey scale displays integrated density contrast.
