Galaxy spatial projected distribution in large-scale structure around Virgo (northern hemisphere) from the NSA-Castignani catalogue (Castignani et al. 2022b). Colour indicates the local DF measured for each galaxy in the region enclosing its 15 near-neighbour galaxies. The red circle highlights the R₂₀₀ radius of the Virgo cluster, while grey circles highlight the (loose and rich) groups from the galaxy group catalogue of Kourkchi & Tully (2017, in the velocity range 500 < v_r < 3300 km s⁻¹; the circle sizes correspond to the projected virial radius of the groups described in that work). The grey lines highlight the filaments of the Castignani et al. (2022a,b) catalogue: Leo Minor F, Canes Venatici F, Bootes F, Ursa Major Cloud, Leo II B F, Leo II A F, Virgo III F, Leo Minor B F, W–M Sheet, NGC 5353/4 F, Serpens F, Draco F, and Coma Berenices F.
