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…
Quantifying and controlling biases in dark matter halo concentration estimates
C. N. Poveda-Ruiz, J. E. Forero-Romero, J. C. Muñoz-Cuartas
We use bootstrapping to estimate the bias of concentration estimates on N-body dark matter halos as a function of particle number. We find that algorithms based on the maximum radi…
Galaxy Cluster Mass Reconstruction Project: II. Quantifying scatter and bias using contrasting mock catalogues
L. Old, R. Wojtak, G. A. Mamon +21
This article is the second in a series in which we perform an extensive comparison of various galaxy-based cluster mass estimation techniques that utilise the positions, velocities…
The Redshift Evolution of LCDM Halo Parameters
J. C. Muñoz-Cuartas, Andrea V. Macciò, Stefan Gottlöber +1
We study the mass and redshift dependence of the concentration parameter in Nbody simulations spanning masses from $10^{10} \hMsun$ to $10^{15} \hMsun$ and redshifts from 0 to 2. W…
