APM Cluster

چکیده
We describe the construction of catalogues of galaxy clusters from the APM Galaxy survey using an automated algorithm based on Abell-like selection criteria. We investigate the eeects of varying several parameters in our selection algorithm, including the magnitude range, and radius from the cluster centre used to estimate the cluster richnesses. We quantify the accuracy of the photometric distance estimates by comparing with measured redshifts, and we investigate the stability and completeness of the resulting catalogues. We nd that the angular correlation functions for diierent cluster catalogues are in good agreement with one another, and are also consistent with the observed amplitude of the spatial correlation function of rich clusters.

Correlation Functions of the Apm Clusters of Galaxies
We have found that the two-point correlation function of the APM clusters of galaxies has an amplitude much higher than that claimed by the APM group. As the richness limit increases from R = 53 to 80, the correlation length increases from 17.5 to 28.9 hMpc. This indicates that the richness dependence of the APM cluster correlation function is also much stronger than what the APM group has repo...
متن کاملTesting ansätze for quasi - nonlinear clustering : the linear APM power spectrum
We compare the accuracy of published formulae that transform the linear perturbation theory power spectrum into the nonlinear regime against the results of an ensemble of large N-body simulations. We find that the modified transformation given by Jain et al.(1995) performs well for initial fluctuations that have a power law power spectrum, but is less succesful for scale dependent spectra. The ...
متن کاملThe APM cluster - galaxy cross - correlation function : Constraints on Ω and galaxy bias
We estimate the cluster-galaxy cross-correlation function (ξcg), from the APM galaxy and galaxy cluster surveys. We obtain estimates both in real space from the inversion of projected statistics and in redshift space using the galaxy and cluster redshift samples. The amplitude of ξcg is found to be almost independent of cluster richness. At large separations, r ∼> 5 h Mpc ( h = H0/100km s , whe...
متن کاملReconstructing the spectrum of the pregalactic density field from astronomical data
In this paper we evaluate the spectrum of the pregalactic density field on scales 1h−1Mpc < r < 100h−1Mpc from a variety of astronomical data. We start with the APM data on the projected angular correlation function, w(θ), in six narrow magnitude bins and check whether possible evolutionary effects can affect inversion of the w(θ) data in terms of the underlying power spectrum. This is done by ...

متن کاملThe APM/Matched-Filter Cluster Catalog
A catalog of nearby clusters in the 5800 deg area in the southern Galactic cap is constructed by applying a matched-filter clusterfinding algorithm to the sample of 3.3 million galaxies from the APM Galaxy Survey. I have preliminarily detected more than 4000 cluster candidates with estimated redshift of less than 0.2 and with richness similar to those of ACO clusters. Generally, a good correspo...
