J-PLUS: On the identification of new cluster members in the double galaxy cluster A2589 & A2593 using PDFs

Understand

We aim to use multi-band imaging from the Phase-3 Verification Data of the J-PLUS survey to derive accurate photometric redshifts (photo-z) and look for potential new members in the surroundings of the nearby galaxy clusters A2589 (z=0.0414) & A2593 (z=0.0440), using redshift probability distribution functions.

• The ultimate goal is to demonstrate the usefulness of a 12-band filter system in the study of large-scale structure in the local universe.
• We present an optimized pipeline for the estimation of photo-z in clusters of galaxies.
• We tested our photo-z with a sample of 296 spectroscopically confirmed cluster members with a magnitude of <r>= 16.6 and redshift <z>=0.041.
