Modeled noise-free y-map of the filamentary structures around the Virgo Cluster, which is also smoothed with the Planck beam (Sect. 4.1), shown on the left. Projection effects for each stated filament can be realized by comparing with Fig. 1. Constructed galaxy density map from the point locations (Sect. 2.1) by using get_interp_weights() function in HEALPY module and smoothing with a Gaussian beam whose FWHM is ≈30 arcmin, shown on the right. Both maps are centered on the Virgo Cluster.
