Galaxy properties as a function of environment in the VUDS+ sample. Left: relationship between SFR and log(1 + δgal) for the 6730 galaxies in the VUDS+ spectroscopic sample. The backdrop shows the number density at a given SFR and log(1 + δgal) value for all galaxies in the sample and the light blue, green, red, and dark blue datapoints and lines show median values in each bin in log(1 + δgal) for galaxies in the CFHTLS-D1, ECDFS, COSMOS, and the full combined VUDS+ sample, respectively. Uncertainties reflect errors on the median values. The vertical dashed lines indicate the “Intermediate” and “Peak” regions of the log(1 + δgal) distributions (see Sect. 3.1), with all values lower than log(1 + δgal) = 0.22 being considered “Field" galaxies. The “All VUDS+” sample can be plotted over a larger dyanamic range in log(1 + δgal) relative to the individual field samples due to its larger sample size. A weak but highly significant positive correlation is observed (see Sect. 3.1). Right: as in the left panel, but now plotted for stellar mass (M*) and log(1 + δgal). Again, a weak but highly significant positive correlation is observed between M* and log(1 + δgal)
