Left panel: spatial distribution of galaxies in a thin angular slice (1 deg) inside our mock lightcone. Each galaxy with M_stellar > 10¹⁰ M_⊙ h⁻¹ is shown as a black dot. The contribution of peculiar velocities is not included. Right panel: same, but including the peculiar velocities in the estimation of the redshift. The clustering is enhanced on large scales due to coherent bulk motions, whereas it is damped on small scales due to random motions inside dark matter haloes.
