Planck list of high redshift source candidates (PHZ)

The Planck list of high redshift source candidates (PHZ) is a list of 2151 sources located in the cleanest 26% of the sky and identified as point sources exhibiting an excess in the submillimetre compared to their environment. It has been built using the 48 months ofPlanck data at 857, 545, 353, and 217 GHz, combined with the 3THz IRAS data, as described in Planck 2015 results XXXIX. These sources are considered as highz source candidates (z>1.52), given the very low contamination by Galactic cirrus, and their typical colourcolour ratios. A subsample of the PHZ list has already been followedup with Herschel, and chararcterized as overdensities of red galaxies for more than 93% of the population, and as strongly lensed galaxies in 3% of the cases, as detailed in Planck 2013 results XXVIII.
