    Dahle, Håkon; Aghanim, Nabila; Guennou, L.; Hudelot, P.; Kneissl, R.; Pointecouteau, E.; Beelen, Anita; Bayliss, M; Douspis, M.; Nesvadba, N.; Hempel, A.; Gronke, Max Balthasar; Burenin, R.; Dole, H.; Harrison, Debbie; Mazzotta, P.; Sunyaev, R (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    As part of an all-sky follow-up of the Planck catalogue of Sunyaev-Zeldovich (SZ) cluster candidates detected in the first 14 months of data, we are observing cluster candidates in the southern sky in the optical imaging ...
