Distortion of Infall Regions in Redshift Space-I

Mohamed H. Abdullah, Elizabeth A. Praton, Gamal B. Ali

We show that spherical infall models (SIMs) can better describe some galaxy clusters in redshift slice space than in traditional axially-convolved projection space. This is because…

Studying the Dynamical Properties of 20 Nearby Galaxy Clusters

Mohamed H. Abdullah, Gamal B. Ali, H. A. Ismail +1

Using SDSS-DR7, we construct a sample of 42382 galaxies with redshifts in the region of 20 galaxy clusters. Using two successive iterative methods, the adaptive kernel method and t…

The 2XMMi/SDSS Galaxy Cluster Survey. III. Clusters associated with spectroscopically targeted luminous red galaxies in SDSS-DR10

A. Takey, A. Schwope, G. Lamer

We present a sample of 383 X-ray selected galaxy groups and clusters with spectroscopic redshift measurements (up to z ~ 0.79) from the 2XMMi/SDSS Galaxy Cluster Survey. The X-ray…
