Optical confirmation and redshift estimation of the Planck cluster candidates overlapping the Pan-STARRS Survey

Optical confirmation and redshift estimation of the Planck cluster candidates overlapping the Pan-STARRS Survey

We report results of a study of Planck Sunyaev–Zel'dovich effect selected galaxy cluster candidates using the Panoramic Survey Telescope & Rapid Response System (Pan-STARRS) imaging data. We first examine 150 Planck-confirmed galaxy clusters with spectroscopic redshifts to test our algorithm for identifying optical counterparts and measuring their redshifts; our redshifts …
