The XXL Survey: XXIII. The Mass Scale of XXL Clusters from Ensemble Spectroscopy
A. Farahi, V. Guglielmo, A. E. Evrard +34
An X-ray survey with the XMM-Newton telescope, XMM-XXL, has identified hundreds of galaxy groups and clusters in two 25 deg fields. Combining spectroscopic and X-ray observatio…
Weak lensing study of 16 DAFT/FADA clusters: substructures and filaments
Nicolas Martinet, Douglas Clowe, Florence Durret +7
While our current cosmological model places galaxy clusters at the nodes of a filament network (the cosmic web), we still struggle to detect these filaments at high redshifts. We p…
The XXL Survey: I. Scientific motivations - XMM-Newton observing plan - Follow-up observations and simulation programme
M. Pierre, F. Pacaud, C. Adami +89
We present the XXL Survey, the largest XMM programme totaling some 6.9 Ms to date and involving an international consortium of roughly 100 members. The XXL Survey covers two extrag…
The XXL Survey. II. The bright cluster sample: catalogue and luminosity function
F. Pacaud, N. Clerc, P. A. Giles +40
Context. The XXL Survey is the largest survey carried out by the XMM-Newton satellite and covers a total area of 50 square degrees distributed over two fields. It primarily aims at…
The mass profile and dynamical status of the z~0.8 galaxy cluster LCDCS 0504
L. Guennou, A. Biviano, C. Adami +34
Constraints on the mass distribution in high-redshift clusters of galaxies are not currently very strong. We aim to constrain the mass profile, M(r), and dynamical status of the $z…
Structure and substructure analysis of DAFT/FADA galaxy clusters in the [0.4-0.9] redshift range
L. Guennou, C. Adami, F. Durret +29
We analyse the structures of all the clusters in the DAFT/FADA survey for which XMM-Newton and/or a sufficient number of galaxy redshifts in the cluster range is available, with th…
VIPERS: An Unprecedented View of Galaxies and Large-Scale Structure Halfway Back in the Life of the Universe
L. Guzzo, U. Abbas, C. Adami +48
The VIMOS Public Extragalactic Redshift Survey (VIPERS) is an ongoing ESO Large Programme to map in detail the large-scale distribution of galaxies at 0.5 < z <1.2. With a combinat…
Diffuse light in the young cluster of galaxies CL J1449+0856 at z=2.07
C. Adami, F. Durret, L. Guennou +1
Cluster properties do not seem to be changing significantly during their mature evolution phase, for example they do not seem to show strong dynamical evolution at least up to z~0.…
The VIMOS Public Extragalactic Redshift Survey (VIPERS): spectral classification through Principal Component Analysis
A. Marchetti, B. R. Granett, L. Guzzo +51
We develop a Principal Component Analysis aimed at classifying a sub-set of 27,350 spectra of galaxies in the range 0.4 < z < 1.0 collected by the VIMOS Public Extragalactic Redshi…
Comparison of the properties of two fossil groups of galaxies with the normal group NGC 6034 based on multiband imaging and optical spectroscopy
C. Adami, S. Jouvel, L. Guennou +9
We collected multiband imaging and spectroscopy for two fossil groups (RX J1119.7+2126 and 1RXS J235814.4+150524) and one normal group (NGC 6034). We computed photometric redshifts…
Intracluster light in clusters of galaxies at redshifts 0.4<z<0.8
L. Guennou, C. Adami, C. Da Rocha +27
The study of intracluster light can help us to understand the mechanisms taking place in galaxy clusters, and to place constraints on the cluster formation history and physical pro…
Galaxy cluster searches based on photometric redshifts in the four CFHTLS Wide fields
F. Durret, C. Adami, A. Cappi +19
We 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. Thi…
A search for faint low surface brightness galaxies in the relaxed cluster Abell 496
Melville P. Ulmer, Christophe Adami, Florence Durret +2
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…
The XMM-LSS survey: optical assessment and properties of different X-ray selected cluster classes
C. Adami, A. Mazure, M. Pierre +29
XMM and Chandra opened a new area for the study of clusters of galaxies. Not only for cluster physics but also, for the detection of faint and distant clusters that were inaccessib…
The DAFT/FADA survey. I.Photometric redshifts along lines of sight to clusters in the z=[0.4,0.9] interval
L. Guennou, C. Adami, M. P. Ulmer +20
As a contribution to the understanding of the dark energy concept, the Dark energy American French Team (DAFT, in French FADA) has started a large project to characterize statistic…
Galaxy cluster searches by photometric redshifts in the CFHTLS
C. Adami, F. Durret, C. Benoist +17
In order to enlarge publicly available optical cluster catalogs, in particular at high redshift, we have performed a systematic search for clusters of galaxies in the CFHTLS. We us…
