Descripción
Context. S uzaku and Chandra X-ray observations detected a new cluster of galaxies, Suzaku J1759−3450, at a redshift z = 0.13. It is located behind the Milky Way, and the high Galactic dust extinction renders it nearly invisible at optical wavelengths. Aims. We attempt here to confirm the galaxy cluster with near-infrared imaging observations and to characterize its central member galaxies. Methods. Images from the VVV survey were used to detect candidate member galaxies of Suzaku J1759−3450 within the central region of the cluster up to 350 kpc from the X-ray peak emission. Color–magnitude diagrams, color–color diagrams, and morphology criteria allowed us to select the galaxies among the numerous foreground sources. Results. Fifteen candidate cluster members were found very close to a modeled red-sequence at the redshift of the cluster. Five members are extremely bright, and one is possibly a cD galaxy. The asymmetry in the spatial distribution of the galaxies with respect to the X-ray peak emission is an indicator that this cluster is still suffering a virialization process. Conclusions. Our investigation of Suzaku J1759−3450 demonstrates the potential of the VVV survey to study the hidden population of galaxies in the zone of avoidance.
