Towards a realistic population of simulated galaxy groups and clusters
Amandine M. C. Le Brun, Ian G. McCarthy, Joop Schaye +1
We present a new suite of large-volume cosmological hydrodynamical simulations called cosmo-OWLS. They form an extension to the OverWhelmingly Large Simulations (OWLS) project, and…
The thermal Sunyaev Zel'dovich effect power spectrum in light of Planck
Ian G. McCarthy, Amandine M. C. Le Brun, Joop Schaye +1
(Abridged) The amplitude of the thermal Sunyaev Zel'dovich effect (tSZ) power spectrum is extremely sensitive to the abundance of galaxy clusters and therefore to fundamental cosmo…
The similarity of the stellar mass fractions of galaxy groups and clusters
J. M. Budzynski, S. E. Koposov, I. G. McCarthy +1
We employ a large sample of 20171 optically-selected groups and clusters at 0.15 < z < 0.4 in the SDSS to investigate how the stacked stellar mass fraction varies across a wide ran…
The impact of baryonic processes on the two-point correlation functions of galaxies, subhaloes and matter
Marcel P. van Daalen, Joop Schaye, Ian G. McCarthy +2
The observed clustering of galaxies and the cross-correlation of galaxies and mass provide important constraints on both cosmology and models of galaxy formation. Even though the d…
Are group- and cluster-scale dark matter halos over-concentrated?
M. W. Auger, J. M. Budzynski, V. Belokurov +2
We investigate the relationship between the halo mass, M_200, and concentration, c, for a sample of 26 group- and cluster-scale strong gravitational lenses. In contrast with previo…
The Hot and Energetic Universe: AGN feedback in galaxy clusters and groups
J. H. Croston, J. S. Sanders, S. Heinz +25
Mechanical feedback via Active Galactic Nuclei (AGN) jets in the centres of galaxy groups and clusters is a crucial ingredient in current models of galaxy formation and cluster evo…
