Hybrid photometric redshifts for sources in the COSMOS and XMM-LSS fields

Autor: P W Hatfield, M J Jarvis, N Adams, R A A Bowler, B Häußler, K J Duncan

In this paper we present photometric redshifts for 2.7 million galaxies in the XMM-LSS and COSMOS fields, both with rich optical and near-infrared data from VISTA and HyperSuprimeCam. Both template fitting (using galaxy and Active Galactic Nuclei tem
