Fig. 12


The IR LFs of three different regions in the A1763 supercluster: core (red dots), filament (blue squares), and outskirts (green stars). 1σ error bars based on 100 bootstrap re-samplings are shown. All IR LFs are corrected for purity and completeness in the corresponding regions. Counts have been multiplied by the fractions of non-AGN galaxies in each LIR-bin and in each region to remove the AGN contribution from the IR LFs. The IR LFs of the upper (respectively, lower) panels have been obtained using the z ∪ zp sample (respectively, z sample) of supercluster members. Left panels show the number densities of IR-emitting galaxies. Lines represent the best-fit power-law functions to the IR LFs. In the right panels, the number densities of IR galaxies have been normalized by the average number densities of galaxies with a r-band luminosity  ≥ 7 × 109   L within each region.
