Left panel: Number of galaxies of a given type and with one or more massive neighbors (stellar mass-ratio >1:10) within 0.5×R₂₀₀ during the last 3 Gyr of the galaxy history, normalized by the total number of galaxies of all types and with one or more massive neighbors at the five different specific redshift z = 2, 1.5, 1, 0.5 and 0. We only consider here the central galaxies in our sample. Right panel: Mean net accretion rate within the last 1 Gyr onto the galactic disk of our selected sample of galaxies at the five different specific redshift z = 2, 1.5, 1, 0.5, 0. Here, we consider all the central galaxies in our sample (i.e., with number of nearest neighbors ≥0). Shaded areas are defined by the 25th–75th interquartile range of the data at each redshift. We divide our galaxies into the four different types, as described in Sect. 5.1.
