The youth of the intracluster medium. I. A non-parametric characterisation of the gas and electron number density profiles of protoclusters

David Vallés-Pérez, Annalisa Bonafede, Klaus Dolag +3

Context. Protoclusters of galaxies are the earliest phase in the assembly of galaxy clusters and can provide invaluable information about plasma physics, cosmic magnetism, and cosm…

The SKA View of Cool-core Clusters: Evolution of Radio Mini-halos and AGN Feedback

Myriam Gitti, Paolo Tozzi, Francesco Ubertosi +12

In about 70 per cent of relaxed, cool-core galaxy clusters, the brightest cluster galaxy (BCG) is radio loud, showing non-thermal radio jets and lobes ejected by the central active…

A big red dot at cosmic noon

Federica Loiacono, Roberto Gilli, Marco Mignoli +22

We report the discovery of a little red dot (LRD), dubbed BiRD ('big red dot'), at in the field around the quasar SDSSJ1030+0524. Using NIRCam images, we identifie…

Feeding and feedback processes in the Spiderweb proto-intracluster medium

M. Lepore, L. Di Mascolo, P. Tozzi +15

We present the detailed analysis of the thermal, diffuse emission of the proto-intracluster medium (ICM) detected in the halo of the Spiderweb Galaxy at z=2.16, within a radius of…

X-ray properties and obscured fraction of AGN in the J1030 Chandra field

Matilde Signorini, Stefano Marchesi, Roberto Gilli +13

The 500ks Chandra ACIS-I observation of the field around the quasar SDSS J1030+0524 is currently the 5th deepest extragalactic X-ray survey. The rich multi-band coverage o…

Physical cool-core condensation radius in massive galaxy clusters

Lei Wang, Paolo Tozzi, Heng Yu +2

We investigate the properties of cool cores in an optimally selected sample of 37 massive and X-ray-bright galaxy clusters, with regular morphologies, observed with Chandra. We mea…
