The GOGREEN survey: the internal dynamics of clusters of galaxies at redshift 0.9-1.4
A. Biviano, R. F. J. van der Burg, M. L. Balogh +20
We aim to determine the mass, velocity anisotropy, and pseudo phase-space density profiles (M(r), beta(r), and Q(r), respectively) of clusters of galaxies at the highest redshifts…
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…
Galaxy Cluster Mass Reconstruction Project - IV. Understanding the effects of imperfect membership on cluster mass estimation
R. Wojtak, L. Old, G. A. Mamon +17
The primary difficulty in measuring dynamical masses of galaxy clusters from galaxy data lies in the separation between true cluster members from interloping galaxies along the lin…
Galaxy Cluster Mass Reconstruction Project: III. The impact of dynamical substructure on cluster mass estimates
L. Old, R. Wojtak, F. R. Pearce +14
With the advent of wide-field cosmological surveys, we are approaching samples of hundreds of thousands of galaxy clusters. While such large numbers will help reduce statistical un…
Galaxy Cluster Mass Reconstruction Project: I. Methods and first results on galaxy-based techniques
L. Old, R. A. Skibba, F. R. Pearce +18
This paper is the first in a series in which we perform an extensive comparison of various galaxy-based cluster mass estimation techniques that utilise the positions, velocities an…
Brighter galaxy bias: underestimating the velocity dispersions of galaxy clusters
L. Old, M. E. Gray, F. R. Pearce
We study the systematic bias introduced when selecting the spectroscopic redshifts of brighter cluster galaxies to estimate the velocity dispersion of galaxy clusters from both sim…
