Clusters of galaxies are at the intersection of cosmic filaments and are still accreting galaxies and groups along these preferential directions, but, because of their relatively low contrast on the sky, they are difficult to detect (unless a large a

Galaxy clusters in the SDSS Stripe 82 based on galaxy photometric redshifts

Autor: Durret, Florence, Adami, Christophe, Bertin, Emmanuel, Hao, Jiangang, Marquez, Isabel, Martinet, Nicolas, Maurogordato, Sophie, Sauvaget, Tabatha, Scepi, Nicolas, Takey, Ali, Ulmer, Melville P.

Based on a recent photometric redshift galaxy catalogue, we have searched for galaxy clusters in the Stripe~82 region of the Sloan Digital Sky Survey by applying the Adami & MAzure Cluster FInder (AMACFI). Extensive tests were made to fine-tune the A

This document summarizes the results of a community-based discussion of the potential science impact of the Mayall+BigBOSS highly multiplexed multi-object spectroscopic capability. The KPNO Mayall 4m telescope equipped with the DOE- and international

A search for faint low surface brightness galaxies in the relaxed cluster Abell 496

Autor: Ulmer, Melville P., Adami, Christophe, Durret, Florence, Ilbert, Olivier, Guennou, Loic

Cluster faint low surface brightness galaxies (fLSBs) are difficult to observe. Consequently, their origin, physical properties and number density are not well known. After a first search for fLSBs in the highly substructured Coma cluster, we present

A weak lensing study of the Coma cluster

Autor: Gavazzi, Raphael, Adami, Christophe, Durret, Florence, Cuillandre, Jean-Charles, Ilbert, Olivier, Mazure, Alain, Pello, Roser, Ulmer, Melville P.

Due to observational constraints, dark matter determinations in nearby clusters based on weak lensing are still extremely rare, in spite of their importance for the determination of cluster properties independent of other methods. We present a weak l
