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…
