  • The Fraction of Cool-core Clusters in X-Ray versus SZ Samples Using Chandra Observations 
    Andrade-Santos, F.; Jones, Christine; Forman, William R.; Lovisari, Lorenzo; Vikhlinin, Alexey; van Weeren, Reinout J.; Murray, Stephen S.; Arnaud, Monique; Pratt, Gabriel W.; Démoclès, J.; Kraft, Ralph; Mazzotta, P.; Böhringer, H.; Chon, Gayoung; Giacintucci, Simona; Clarke, Tracy E.; Borgani, S.; David, L.; Douspis, M.; Pointecouteau, E.; Dahle, Håkon; Brown, Shea; Aghanim, Nabila; Rasia, Elena (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    We derive and compare the fractions of cool-core clusters in the Planck Early Sunyaev–Zel'dovich sample of 164 clusters with $z\leqslant 0.35$ and in a flux-limited X-ray sample of 100 clusters with $z\leqslant 0.30$, using ...
  • The stellar mass function of galaxies in Planck-selected clusters at 0.5 < z < 0.7: new constraints on the timescale and location of satellite quenching 
    van der Burg, Remco F.J.; McGee, Sean; Aussel, Hervé; Dahle, Håkon; Arnaud, Monique; Pratt, Gabriel W.; Muzzin, Adam (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    We study the abundance of star-forming and quiescent galaxies in a sample of 21 clusters at 0.5 <  z <  0.7, detected with the Planck satellite. Thanks to the large volume probed by Planck, these systems are extremely ...
