NIKA2 observations of 3 low-mass galaxy clusters at : pressure profile and - relation
R. Adam, M. Ricci, D. Eckert +64
Three galaxy clusters selected from the XXL X-ray survey at high redshift and low mass ( and M) were observed with NIKA2 to imag…
The XXL Survey XXV. Cosmological analysis of the C1 cluster number counts
F. Pacaud, M. Pierre, J. -B. Melin +25
Context. We present an estimation of cosmological parameters with clusters of galaxies. Aims. We constrain the , , and parameters from a stand-alone sample of X-ray c…
The XXL Survey: XXII. The XXL-North spectrophotometric sample and galaxy stellar mass function in X-ray detected groups and clusters
V. Guglielmo, B. M. Poggianti, B. Vulcani +42
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. 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…
