Probing Cosmology with Dark Matter Halo Sparsity Using X-ray Cluster Mass Measurements
P. S. Corasaniti, S. Ettori, Y. Rasera +5
We present a new cosmological probe for galaxy clusters, the halo sparsity. This characterises halos in terms of the ratio of halo masses measured at two different radii and carrie…
Spectroscopic confirmation and velocity dispersions for twenty Planck galaxy clusters at 0.16<z<0.78
S. Amodeo, S. Mei, S. A. Stanford +8
We present Gemini and Keck spectroscopic redshifts and velocity dispersions for twenty clusters detected via the Sunyaev-Zel'dovich (SZ) effect by the Planck space mission, with es…
Calibrating the Planck Cluster Mass Scale with Cluster Velocity Dispersions
Stefania Amodeo, Simona Mei, Spencer A. Stanford +7
We measure the Planck cluster mass bias using dynamical mass measurements based on velocity dispersions of a subsample of 17 Planck-detected clusters. The velocity dispersions were…
On the evolution of the entropy and pressure profiles in X-ray luminous galaxy clusters at z > 0.4
V. Ghirardini, S. Ettori, S. Amodeo +2
Galaxy clusters are the most recent products of hierarchical accretion over cosmological scales. The gas accreted from the cosmic field is thermalized inside the cluster halo. Gas…
