The mass-size relation of galaxy clusters
O. Contigiani, Y. M. Bahé, H. Hoekstra
The outskirts of accreting dark matter haloes exhibit a sudden drop in density delimiting their multi-stream region. Due to the dynamics of accretion, the location of this physical…
Stellar splashback: the edge of the intracluster light
Alis J. Deason, Kyle A. Oman, Azadeh Fattahi +8
We examine the outskirts of galaxy clusters in the C-EAGLE simulations to quantify the `edges' of the stellar and dark matter distribution. The radius of the steepest slope in the…
Dynamical masses of brightest cluster galaxies II: constraints on the stellar IMF
S. I. Loubser, H. Hoekstra, A. Babul +2
We use stellar and dynamical mass profiles, combined with a stellar population analysis, of 32 brightest cluster galaxies (BCGs) at redshifts of 0.05 0.30, to place c…
The stellar mass function and evolution of the density profile of galaxy clusters from the Hydrangea simulations at
Syeda Lammim Ahad, Yannick M. Bahé, Henk Hoekstra +2
Galaxy clusters are excellent probes to study the effect of environment on galaxy formation and evolution. Along with high-quality observational data, accurate cosmological simulat…
A homogeneous measurement of the delay between the onsets of gas stripping and star formation quenching in satellite galaxies of groups and clusters
Kyle A. Oman, Yannick M. Bahé, Julia Healy +3
We combine orbital information from N-body simulations with an analytic model for star formation quenching and SDSS observations to infer the differential effect of the group/clust…
Dynamical masses of brightest cluster galaxies I: stellar velocity anisotropy and mass-to-light ratios
S. I. Loubser, A. Babul, H. Hoekstra +3
We investigate the stellar and dynamical mass profiles in the centres of 25 brightest cluster galaxies (BCGs) at redshifts of 0.05 0.30. Our spectroscopy enables us t…
