cds-question@unistra.frgalaxy-clustersredshiftedWe have developed a method for detecting clusters in large imaging surveys, based on the detection of structures in galaxy density maps made in slices of photometric redshifts. This method was first applied to the Canada France Hawaii Telescope Legacy Survey (CFHTLS) Deep 1 field by Mazure et al. (2007A&A...467...49M), then to all the Deep and Wide CFHTLS fields available in the T0004 data release by Adami et al. (2010, Cat. J/A+A/509/81). The validity of the cluster detection rate was estimated by applying the same procedure to galaxies from the Millennium simulation. Here we analyse with the same method the full CFHTLS Wide survey, based on the T0006 data release. In a total area of 154deg^2^, we have detected 4061 candidate clusters at 3sigma or above (6802 at 2sigma and above), in the redshift range 0.1<=z<=1.15, with estimated mean masses between 1.3x10^14^ and 12.6x10^14^M_{sun}_. We compare our detections with those made in various CFHTLS analyses with other methods. By stacking a subsample of clusters, we show that this subsample has typical cluster characteristics (colour-magnitude relation, galaxy luminosity function). We also confirm that the cluster-cluster correlation function is comparable to that obtained for other cluster surveys and analyze large scale filamentary galaxy distributions. We have increased the number of known optical high redshift cluster candidates by a large factor, an important step towards obtaining reliable cluster counts to measure cosmological parameters. The clusters that we detect behave as expected for a sample of clusters fed by filaments at the intersection of which they are located.2011A&A...535A..65Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/535/A65CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/509/A81 : Candidate clusters detected in six CFHTLS fields (Adami+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/535/A65https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/535/A65http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/535/A65https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/535/A65https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/535/A65http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/535/A65GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/535/A65/clusters (Cluster positions and magnitudes in the CFHTLS wide fields 1--4)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/535/A65/clusters?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/535/A65/clusters?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/535/A65/clusters?GETtext/xml+votable180.050000true30.2479-10.57820.0055555555555555564/1104 1191 2298 2559 5/2687 2856 2858-2859 2862 2944-2945 4372-4373 4375 4420-4422 4424-4425 4758-4759 9151 9198 10230 10233 10235 6/10741-10743 10745 10747 11092-11093 11402-11403 11428 11430-11431 11442 11788 11792 17497 17525 17692-17694 17705 17708-17710 17712-17714 17728 17730 19021 19023 19025-19027 19030 19047 19053 19153 19156-19157 19240 19242 21840-21841 21843-21844 27298 27304 36599 36603 36747 36750 36786 36798 40909-40911 40926 40929 40931https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/535/A65?format=asciiOpticaldefaultJ/A+A/535/A65/clustersCluster positions and magnitudes in the CFHTLS wide fields 1--4recnoRecord number assigned by the VizieR team.
