  • Optical validation and characterization of Planck PSZ1 sources at the Canary Islands observatories: I. First year of ITP13 observations 
    Barrena, R.; Streblyanska, A.; Ferragamo, A.; Rubiño-Martín, J. A.; Aguado-Barahona, A.; Tramonte, D.; Génova-Santos, R. T.; Hempel, A.; Lietzen, H.; Aghanim, Nabila; Arnaud, M.; Böhringer, H.; Chon, G.; Démoclès, J.; Dahle, Håkon; Douspis, M.; Lasenby, A. N.; Mazzotta, P.; Melin, J. B.; Pointecouteau, E.; Pratt, G. W.; Rossetti, M.; van der Burg, R. F. J. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    We have identified new clusters and characterized previously unknown Planck Sunyaev–Zeldovich (SZ) sources from the first Planck catalogue of SZ sources (PSZ1). The results presented here correspond to an optical follow-up ...
  • Prospects for high-z cluster detections with Planck, based on a follow-up of 28 candidates using MegaCam at CFHT 
    van der Burg, R. F. J.; Aussel, H; Pratt, G. W.; Arnaud, Monique; Melin, J.-B.; Aghanim, Nabila; Barrena, R.; Dahle, Håkon; Douspis, M.; Ferragamo, A; Fromenteau, S.; Herbonnet, R.; Hurier, G.; Pointecouteau, E.; Rubiño-Martín, J. A.; Streblyanska, A (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    The Planck catalogue of SZ sources limits itself to a significance threshold of 4.5 to ensure a low contamination rate by false cluster candidates. This means that only the most massive clusters at redshift z> 0.5, and in ...
