Description
We present a new (2+1)D galaxy cluster finder based on photometric redshifts called Wavelet Z Photometric (WaZP), that searches for clusters in wavelet-based density maps of galaxies selected in photometric redshift space without any assumption on the cluster galaxy populations. This cluster finder was applied to DES first year (Y1A1) data, where the results were compared to clusters detected by the South Pole Telescope (SPT) survey and the redMaPPer cluster finder, the latter based on the same photometric data. We intend to run WaZP on DC2 and evaluate its performance on LSST like data and explore its physical and cosmological applications.
