The fraction of galaxies bound in groups in the nearby Universe is high (50% at z~0). Systematic studies of galaxy properties in groups are important in order to improve our unders…
The XXL survey XV: Evidence for dry merger driven BCG growth in XXL-100-GC X-ray clusters
S. Lavoie, J. P. Willis, J. Democles +33

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: VI. The 1000 brightest X-ray point sources
S. Fotopoulou, F. Pacaud, S. Paltani +36
X-ray extragalactic surveys are ideal laboratories for the study of the evolution and clustering of active galactic nuclei (AGN). The XXL Survey spans two fields of a combined 50 $…
The XXL Survey VIII: MUSE characterisation of intracluster light in a z0.53 cluster of galaxies
C. Adami, E. Pompei, T. Sadibekova +11
Within a cluster, gravitational effects can lead to the removal of stars from their parent galaxies. Gas hydrodynamical effects can additionally strip gas and dust from galaxies. T…
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 VIMOS Public Extragalactic Redshift Survey (VIPERS). Environmental effects shaping the galaxy stellar mass function
I. Davidzon, O. Cucciati, M. Bolzonella +38
We exploit the first public data release of VIPERS to investigate environmental effects in galaxy evolution between and . The large number of spectroscopic redshift…
The evolution of the cluster optical galaxy luminosity function between z=0.4 and 0.9 in the DAFT/FADA survey
Nicolas Martinet, Florence Durret, Loic Guennou +8
We compute optical galaxy luminosity functions (GLFs) in the B, V, R, and I rest-frame bands for one of the largest medium-to-high-redshift (0.4 < z < 0.9) cluster samples to date…
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…
