The detection of galaxy clusters in present and future surveys enables measuring mass-to-light ratios, clustering properties, galaxy cluster abundances and, therefore, constraining cosmological parameters. We present a new technique for detecting galaxy clusters, which is based on the matched filter algorithm from a Bayesian point of view. The method is able to determine the position, redshift and richness of the cluster through the maximization of a filter depending on galaxy luminosity… Expand
Galaxy clusters in the SDSS Stripe 82 based on photometric redshifts
Context. The discovery of new galaxy clusters is important for two reasons. First, clusters are interesting per se, since their detailed analysis allows us to understand how galaxies form and evolveExpand
Euclid preparation
Galaxy cluster counts in bins of mass and redshift have been shown to be a competitive probe to test cosmological models. This method requires an efficient blind detection of clusters from surveysExpand
The Integrated Cluster Finder for the ARCHES project
Context. Clusters of galaxies are important for cosmology and astrophysics. They may be discovered through either the summed optical/IR radiation originating from their member galaxies or via X-rayExpand
Brighter galaxy bias: underestimating the velocity dispersions of galaxy clusters
We study the systematic bias introduced when selecting the spectroscopic redshifts of brighter cluster galaxies to estimate the velocity dispersion of galaxy clusters from both simulated andExpand
The RedGOLD Cluster Detection Algorithm and its Cluster Candidate Catalogue for the CFHT-LS W1
We present RedGOLD (Red-sequence Galaxy Overdensity cLuster Detector), a new optical/NIR galaxy cluster detection algorithm, and apply it to the CFHT-LS W1 field. RedGOLD searches for red-sequenceExpand
Optical galaxy clusters in the Deep Lens Survey
Author(s): Ascaso, B; Wittman, D; Dawson, W | Abstract: We present the first sample of 882 optically selected galaxy clusters in the Deep Lens Survey (DLS), selected with the Bayesian Cluster Finder.Expand
J-PLUS: On the identification of new cluster members in the double galaxy cluster A2589 and A2593 using PDFs
Aims. We aim to use multiband imaging from the Phase-3 Verification Data of the J-PLUS survey to derive accurate photometric redshifts (photo-z) and look for potential new members in the surroundingsExpand
Galaxy Cluster Mass Reconstruction Project: I. Methods and first results on galaxy-based techniques

AMICO: optimized detection of galaxy clusters in photometric surveys
We present AMICO (Adaptive Matched Identifier of Clustered Objects), a new algorithm for the detection of galaxy clusters in photometric surveys. AMICO is based on the Optimal Filtering technique,Expand
maggie: Models and Algorithms for Galaxy Groups, Interlopers and Environment
Redshift distortions make it notoriously difficult to recover real-space galaxy groups from redshift space data. We make use of the previously measured universal distribution of halo interlopers inExpand
