The Cluster-EAGLE project: a comparison of dynamical mass estimators using simulated clusters
Thomas J. Armitage, Scott T. Kay, David J. Barnes +2
Forthcoming large-scale spectroscopic surveys will soon provide data on thousands of galaxy clusters. It is important that the systematics of the various mass estimation techniques…
An application of machine learning techniques to galaxy cluster mass estimation using the MACSIS simulations
Thomas J. Armitage, Scott T. Kay, David J. Barnes
Machine learning (ML) techniques, in particular supervised regression algorithms, are a promising new way to use multiple observables to predict a cluster's mass or other key featu…
The Cluster-EAGLE project: velocity bias and the velocity dispersion - mass relation of cluster galaxies
Thomas Joshua Armitage, David. J. Barnes, Scott. T. Kay +4
We use the Cluster-EAGLE simulations to explore the velocity bias introduced when using galaxies, rather than dark matter particles, to estimate the velocity dispersion of a galaxy…
