Metal enrichment: the apex accretor perspective
S. Molendi, S. Ghizzardi, S. De Grandi +7
Aims. The goal of this work is to devise a description of the enrichment process in large-scale structure that explains the available observations and makes predictions for future…
The evolving cluster cores: Putting together the pieces of the puzzle
S. Molendi, S. De Grandi, M. Rossetti +4
In this work we address the issue of whether the division of clusters in cool cores (CCs) and non-cool cores (NCCs) is due to a primordial difference or to how clusters evolve acro…
Where does the gas fueling star formation in BCGs originate?
S. Molendi, P. Tozzi, M. Gaspari +4
We investigate the relationship between X-ray cooling and star formation in brightest cluster galaxies (BCGs). We present an X-ray spectral analysis of the inner regions, 10-40 kpc…
A textbook example of ram-pressure stripping in the Hydra A/A780 cluster
S. De Grandi, D. Eckert, S. Molendi +7
In the current epoch, one of the main mechanisms driving the growth of galaxy clusters is the continuous accretion of group-scale halos. In this process, the ram pressure applied b…
A critical assessment of the metal content of the ICM
S. Molendi, D. Eckert, S. De Grandi +5
Our goal is to provide a robust estimate of the metal content of the ICM in massive clusters. We make use of published abundance profiles for a sample of ~60 nearby systems, we inc…
New XMM-Newton observation of the Phoenix cluster: properties of the cool core
P. Tozzi, F. Gastaldello, S. Molendi +9
(Abridged) We present a spectral analysis of a deep (220 ks) XMM-Newton observation of the Phoenix cluster (SPT-CL J2344-4243), which we also combine with Chandra archival ACIS-I d…
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 structure of Abell 1351: a bimodal galaxy cluster with peculiar diffuse radio emission
R. Barrena, M. Girardi, W. Boschin +2
We aim to review the internal structure and dynamics of the Abell 1351 cluster, shown to host a radio halo with a quite irregular shape. Our analysis is based on radial velocity da…
