Metal Enrichment of the Intra-Cluster Medium: Ram-Pressure Stripping of Cluster Galaxies
W. Domainko, W. Kapferer, S. Schindler +4
We present numerical simulations of the dynamical and chemical evolution of galaxy clusters. X-ray spectra show that the intra-cluster medium contains a significant amount of metal…
Metal Enrichment and Energetics of Galactic Winds in Galaxy Clusters
W. Kapferer, D. Breitschwerdt, W. Domainko +4
We investigate efficiency and time dependence of metal enrichment processes in the Intra-Cluster Medium (ICM). In this presentation we concentrate on the effects of galactic winds.…
Lens magnification by CL0024+1654 in the U and R band
S. Dye, A. N. Taylor, T. R. Greve +6
[ABRIDGED] We estimate the total mass distribution of the galaxy cluster CL0024+1654 from the measured source depletion due to lens magnification in the R band. Within a radius of…
The survival of subhaloes in galaxies and galaxy clusters
Eelco van Kampen
This paper discusses physical and numerical disruption processes acting on subhaloes in galaxy haloes and in galaxy cluster haloes, and compare the effects of these processes on th…
Modelling galaxy clustering at high redshift
Eelco van Kampen
Most phenomenological galaxy formation models show a discrepancy between the predicted Tully-Fisher relation and the luminosity function. We show that this is mainly due to overmer…
Overmerging in N-body simulations
Eelco van Kampen
The aim of this paper is to clarify the notion and cause of overmerging in N-body simulations, and to present analytical estimates for its timescale. Overmerging is the disruption…
