Number counts of the excess of YHK-selected galaxies (per 0.5 Ks mag bin) found in the surroundings of MRC 1017-220 (top panel) and MRC 0156-252 (bottom panel). We first derive reference number counts for the r-YHK (red) and b-YHK (blue) galaxies from the control fields: CF2+GOODS1+GOODS2 and then subtract them from the number counts of the YHK galaxies found in the field of the HzRGs. We assume poissonian errors. Densities are given in sq. deg. (left axis). Excess number of galaxies for each HzRG field (~60 sq. arcmin) is shown on the right axis.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
