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…
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 XIX. A realistic population of simulated X-ray AGN: Comparison of models with observations
E. Koulouridis, L. Faccioli, A. M. C. Le Brun +11
Modern cosmological simulations rely heavily on feedback from active galactic nuclei (AGN) in order to stave off overcooling in massive galaxies and galaxy groups and clusters. An…
