Identification of members in the central and outer regions of galaxy clusters
Ana Laura Serra, Antonaldo Diaferio
The caustic technique measures the mass of galaxy clusters in both their virial and infall regions and, as a byproduct, yields the list of cluster galaxy members. Here we use 100 g…
Measuring the Mass Distribution in Galaxy Clusters
Margaret J. Geller, Antonaldo Diaferio, Kenneth J. Rines. Ana Laura Serra
Cluster mass profiles are tests of models of structure formation. Only two current observational methods of determining the mass profile, gravitational lensing and the caustic tech…
Measuring the Ultimate Mass of Galaxy Clusters: Redshifts and Mass Profiles from the Hectospec Cluster Survey (HeCS)
Kenneth Rines, Margaret J. Geller, Antonaldo Diaferio +1
The infall regions of galaxy clusters represent the largest gravitationally bound structures in a CDM universe. Measuring cluster mass profiles into the infall regions provides…
The Acceleration Scale, Modified Newtonian Dynamics, and Sterile Neutrinos
Antonaldo Diaferio, Garry W. Angus
General Relativity is able to describe the dynamics of galaxies and larger cosmic structures only if most of the matter in the Universe is dark, namely it does not emit any electro…
A WISE View of a Nearby Supercluster A2199
Ho Seong Hwang, Margaret J. Geller, Antonaldo Diaferio +1
We use Wide-field Infrared Survey Explorer (WISE) data covering the entire region (~130 deg^2) of the A2199 supercluster at z=0.03 to study the mid-infrared (MIR) properties of sup…
Weak lensing peak count as a probe of f(R) theories
V. F. Cardone, S. Camera, R. Mainini +4
Weak gravitational lensing by galaxy clusters on faint higher redshift galaxies has been traditionally used to study the cluster mass distribution and as a tool to identify cluster…
