Distribution of galaxies around the Coma cluster region. Left panel: distribution of galaxies in the sky plane (in arbitrary cartesian coordinates), while the right ascensions and declinations are shown as dotted lines. Upper right panel: observed distribution of galaxies along the line of sight. Lower right panel: distribution of galaxies after correction for the redshift space distortions. The redshifts shown in the panels are heliocentric observed redshifts, while the distances are comoving distances given in a CMB frame. Each subcomponent of the Coma cluster is marked as a coloured point and all other galaxies are marked as grey points. The circle around each component is the virial radius (R₂₀₀) of the system.
