Top panel: excess PDF ξ of μ₁ = cos θ₁, the angle between the minor axis of the central galaxy and the direction towards the centre of mass of its satellites, for different central galaxy stellar mass bins, between redshift 0.3 < z < 0.8. Satellites tend to be distributed on the galactic plane of the central and this trend is stronger with the increasing mass of the central. Bottom panel: excess PDF of ν = cos α, the cosine of the angle between the direction of the central’s nearest filament axis and the direction towards the centre of mass of its satellites. Satellites tend to be strongly distributed along filaments. Error bars are 1− σ Poissonian error bars. indicates the median value in each mass bin.
