The XXL Survey: XXIII. The Mass Scale of XXL Clusters from Ensemble Spectroscopy
A. Farahi, V. Guglielmo, A. E. Evrard +34
An X-ray survey with the XMM-Newton telescope, XMM-XXL, has identified hundreds of galaxy groups and clusters in two 25 deg fields. Combining spectroscopic and X-ray observatio…
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…
The XXL Survey: XXII. The XXL-North spectrophotometric sample and galaxy stellar mass function in X-ray detected groups and clusters
V. Guglielmo, B. M. Poggianti, B. Vulcani +42
The fraction of galaxies bound in groups in the nearby Universe is high (50% at z~0). Systematic studies of galaxy properties in groups are important in order to improve our unders…
Large Synoptic Survey Telescope Galaxies Science Roadmap
Brant E. Robertson, Manda Banerji, Michael C. Cooper +47
The Large Synoptic Survey Telescope (LSST) will enable revolutionary studies of galaxies, dark matter, and black holes over cosmic time. The LSST Galaxies Science Collaboration has…
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…
PSZ2LenS. Weak lensing analysis of the Planck clusters in the CFHTLenS and in the RCSLenS
Mauro Sereno, Giovanni Covone, Luca Izzo +3
The possibly unbiased selection process in surveys of the Sunyaev Zel'dovich effect can unveil new populations of galaxy clusters. We performed a weak lensing analysis of the PSZ2L…
Hierarchical inference of the relationship between Concentration and Mass in Galaxy Groups and Clusters
Maggie Lieu, Will M. Farr, Michael Betancourt +3
Mass is a fundamental property of galaxy groups and clusters. In theory weak gravitational lensing will enable an approximately unbiased measurement of mass, but parametric methods…
