Estimating masses of galaxy clusters - a first step in exploring dark matter
[Examensarbete på avancerad nivå]
Masses of galaxy clusters and the cluster mass function (abundance of clusters as a function of cluster masses), have been estimated from the largest cluster catalog of SDSS galaxies using mainly three different interloper removal methods: the maximum velocity approach, the 2-3sigma-clipping approach and the maximum velocity gap approach. In these three approaches the virial mass estimator have been used. The
