Obscured star formation in intermediate-density environments: A Spitzer study of the Abell 901/902 supercluster
A. Gallazzi, E. F. Bell, C. Wolf +23
We explore the amount of obscured star-formation as a function of environment in the A901/902 supercluster at z=0.165 in conjunction with a field sample drawn from the A901 and CDF…
Simulating the high-redshift universe in the sub-mm
Eelco van Kampen
I present various simulations of an on-going large sub-mm survey, SHADES, showing how constraints can be put on galaxy formation models and cosmology from this survey.
Depletion of background galaxies due to the cluster lens CL0024+1654: U and R band observations
O. E. Rognvaldsson, T. R. Greve, J. Hjorth +7
We have obtained U and R band observations of the depletion of background galaxies due to the gravitational lensing of the galaxy cluster CL0024+1654 (z=0.39). The radial depletion…
Properties of galaxy halos in Clusters and Voids
V. Antonuccio-Delogu, U. Becciani, E. van Kampen +5
We use the results of a high resolution N-body simulation to investigate the role of the environment on the formation and evolution of galaxy-sized halos. Starting from a set of co…
Overmerging and M/L ratios in phenomenological galaxy formation models
Eelco van Kampen, Raul Jimenez, John A. Peacock
We show that the discrepancy between the Tully-Fisher relation and the luminosity function predicted by most phenomenological galaxy formation models is mainly due to overmerging o…
Cluster mass estimation from lens magnification
Eelco van Kampen
The surface mass density of a cluster of galaxies, and thus its total mass, can be estimated from its lens magnification. The magnification can be determined from the variation in…
Gravitational Lens Magnification and the Mass of Abell 1689
A. N. Taylor, S. Dye, T. J. Broadhurst +2
We present the first application of lens magnification to measure the absolute mass of a galaxy cluster; Abell 1689. The absolute mass of a galaxy cluster can be measured by the gr…
Properties of galaxy clusters in N-body simulations: Intrinsic properties
Pascal de Theije, Eelco van Kampen, Remco Slijkhuis
We study the influence of the various parameters of scenarios of large-scale structure formation on properties of galaxy clusters, and investigate which cluster properties are most…
A catalogue of galaxy cluster models
Eelco van Kampen, Peter Katgert
We present a technique to construct a fair sample of simulated galaxy clusters, and build such a sample for a specific cosmological structure formation scenario. Conventionally one…
Distribution functions for clusters of galaxies from N-body simulations
Priyamvada Natarajan, Jens Hjorth, Eelco van Kampen
We present the results of an attempt to adapt the distribution function formalism to characterize large-scale structures like clusters of galaxies that form in a cosmological N-bod…
The Shapes of Galaxy Clusters
P. A. M. de Theije, P. Katgert, E. van Kampen
We have reanalyzed a data set of 99 low redshift () Abell clusters and determined their shapes. For this, three different measures are used. We use Monte-Carlo simulatio…
