Caught in the act: diffuse stellar and Ly emission around a halo-less quasar in the assembling cluster CARLA J0800+4029 at z=2
Sofia G. Gallego, Simona Mei, Emanuele Daddi +3
Extended Ly emission is commonly detected around luminous quasars at -3 and traces cold gas in the circumgalactic environment of the AGN. Together with the spatial distr…
Coevolution of halo and quasar properties in dense environments: CARLA J1017+6116 at z=2.8
Sofia G. Gallego, Simona Mei, Christopher Martin +4
Radio-loud active galactic nuclei, in particular radio-loud quasars, are fueled by accretion onto supermassive black holes and are among the most energetic sources in the Universe.…
Spectroscopic confirmation of the galaxy clusters CARLA J0950+2743 at z=2.363, and CARLA-Ser J0950+2743 at z=2.243
Kirill A. Grishin, Simona Mei, Igor V. Chilingarian +6
Galaxy clusters, being the largest gravitationally bound structures in the Universe, are a powerful tool to study mass assembly at different epochs. At z2 they give an unique op…
