MERGHERS Pilot: MeerKAT discovery of diffuse emission in nine massive Sunyaev-Zel'dovich-selected galaxy clusters from ACT
K. Knowles, D. S. Pillay, S. Amodeo +26
The MeerKAT Exploration of Relics, Giant Halos, and Extragalactic Radio Sources (MERGHERS) survey is a planned project to study a large statistical sample of galaxy clusters with t…
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…
The Atacama Cosmology Telescope: A Catalog of > 4000 Sunyaev-Zel'dovich Galaxy Clusters
M. Hilton, C. Sifón, S. Naess +146
We present a catalog of 4195 optically confirmed Sunyaev-Zel'dovich (SZ) selected galaxy clusters detected with signal-to-noise > 4 in 13,211 deg of sky surveyed by the Atacama…
The Kinematic Sunyaev-Zel'dovich Effect with ACT, DES, and BOSS: a Novel Hybrid Estimator
M. Mallaby-Kay, S. Amodeo, J. C. Hill +80
The kinematic and thermal Sunyaev-Zel'dovich (kSZ and tSZ) effects probe the abundance and thermodynamics of ionized gas in galaxies and clusters. We present a new hybrid estimator…
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…
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…
