Clusters and groups of galaxies in 2dF
Listed in IVOA Registry (Virtual Observatory)
We create a new catalogue of groups and clusters, applying the friends-to-friends method to the 2dF GRS final release.
Description
We investigate various selection effects due to the use of a magnitude limited sample. For this purpose we follow the changes in group sizes and mean galaxy number densities within the groups when shifting nearby observed groups to larger distances.
We study the distribution of sizes of dark matter haloes in N-body simulations and compare properties of these haloes and the 2dF groups.
