Sky projected positions of galaxies in the Virgo cluster region. The locations of M87 and M49 are shown with large green and blue dots, respectively, whereas the large green, blue, black and cyan circles represent the virial radii of M87, M49, W, and M clouds, respectively (Boselli et al. 2018). The black square indicates the position of the W plume. Colors indicate the 3D cluster-centric distance from M87: r/R₂₀₀ < 1 (red), 1 < r/R₂₀₀ < 2 (pink), 2 < r/R₂₀₀ < 3 (green), 3 < r/R₂₀₀ < 4 (cyan), and 4 < r/R₂₀₀ < 5 (blue), while gray points represent galaxies at r/R₂₀₀ > 5. We note that the figure shows projected sky positions, whereas the color-coding is based on the three-dimensional distance, so galaxies at large distances can appear close to the cluster in projection (see text for further details).
