Abstract:We present a detailed study of the Planck-selected binary galaxy cluster PLCK G165.7+67.0 (G165; z = 0.348). A multiband photometric catalog is generated that incorporates new imaging from the Large Binocular Telescope/Large Binocular Camera and Spitzer/IRAC to existing imaging. To cope with the different image characteristics, robust methods are applied in the extraction of the matchedaperture photometry. Photometric redshifts are estimated for 143 galaxies in the 4 arcmin 2 field of overlap covered by all th… Show more
