The SKA view of cool-core clusters: evolution of radio mini-halos and AGN feedback
Myriam Gitti, Paolo Tozzi, Gianfranco Brunetti +10
In about 70% of the population of relaxed, cool-core galaxy clusters, the brightest cluster galaxy (BCG) is radio loud, showing non-thermal radio jets and lobes ejected by the cent…
Chandra deep observation of XDCP J0044.0-2033, a massive galaxy cluster at z>1.5
P. Tozzi, J. S. Santos, M. J. Jee +11
We report the analysis of the Chandra observation of XDCP J0044.0-2033, a massive, distant (z=1.579) galaxy cluster discovered in the XDCP survey. The total exposure time of 380 ks…
The reversal of the SF-density relation in a massive, X-ray selected galaxy cluster at z=1.58: results from Herschel
Joana S. Santos, . Bruno Altieri, Ivan Valtchanov +8
Dusty, star-forming galaxies have a critical role in the formation and evolution of massive galaxies in the Universe. Using deep far-infrared imaging in the range 100-500um obtaine…
On the Fe abundance peak formation in cool-core clusters of galaxies: hints from cluster WARPJ1415.1+3612 at z=1.03
Sabrina De Grandi, Joana S. Santos, Mario Nonino +5
We present a detailed study of the iron content of the core of the high-redshift cluster WARPJ1415.1+3612 (z=1.03). By comparing the central Fe mass excess observed in this system,…
The Swift X-ray Telescope Cluster Survey II. X-ray spectral analysis
P. Tozzi, A. Moretti, E. Tundo +7
(Abridged) We present a spectral analysis of a new, flux-limited sample of 72 X-ray selected clusters of galaxies identified with the X-ray Telescope (XRT) on board the Swift satel…
Intra Cluster Light properties in the CLASH-VLT cluster MACS J1206.2-0847
V. Presotto, M. Girardi, M. Nonino +46
We aim at constraining the assembly history of clusters by studying the intra cluster light (ICL) properties, estimating its contribution to the fraction of baryons in stars, f*, a…
