Cosmological Constraint on and from Cluster Abundances using the Optical-Spectroscopic SDSS Catalog
Mohamed H. Abdullah, Anatoly Klypin, Gillian Wilson
We derive cosmological constraints on the matter density, \om, and the amplitude of fluctuations, \sig, using , a catalog of 1800 galaxy clusters we identified…
The Rest-frame -band Luminosity Function of Red Sequence Galaxies in Clusters at
Jeffrey C. C. Chan, Gillian Wilson, Gregory Rudnick +22
We present results on the rest-frame -band luminosity functions (LF) of red sequence galaxies in seven clusters at 1.0 < z < 1.3 from the Gemini Observations of Galaxies in Rich…
GalWeight Application: A publicly-available catalog of dynamical parameters of 1,800 galaxy clusters from SDSS-DR13, ()
Mohamed H. Abdullah, Gillian Wilson, Anatoly Klypin +3
Utilizing the SDSS-DR13 spectroscopic dataset, we create a new publicly-available catalog of 1,800 galaxy clusters (GalWeight cluster catalog, ) and a correspon…
GalWeight: A New and Effective Weighting Technique for Determining Galaxy Cluster and Group Membership
Mohamed H. Abdullah, Gillian Wilson, Anatoly Klypin
We introduce GalWeight, a new technique for assigning galaxy cluster membership. This technique is specifically designed to simultaneously maximize the number of bona fide cluster…
