A three-component giant radio halo: the puzzling case of the galaxy cluster Abell 2142
L. Bruno, A. Botteon, T. Shimwell +16
Turbulence introduced into the intra-cluster medium (ICM) through cluster merger events transfers energy to non-thermal components, and can trigger the formation of diffuse synchro…

Junhan Kim, Jack Sayers, Mauro Sereno +23
Galaxy clusters are the products of structure formation through myriad physical processes that affect their growth and evolution throughout cosmic history. As a result, the matter…
CHEX-MATE: Constraining the origin of the scatter in galaxy cluster radial X-ray surface brightness profiles
I. Bartalucci, S. Molendi, E. Rasia +25
We investigate the statistical properties and the origin of the scatter within the spatially resolved surface brightness profiles of the CHEX-MATE sample, formed by 118 galaxy clus…
Optical/X-ray/radio view of Abell 1213: A galaxy cluster with anomalous diffuse radio emission
W. Boschin, M. Girardi, S. De Grandi +5
Context. Abell 1213, a low-richness galaxy system, is known to host an anomalous radio halo detected in data of the VLA. It is an outlier with regard to the relation between the ra…
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…
Does the Fe L-shell blend bias abundance measurements in intermediate-temperature clusters?
G. Riva, S. Ghizzardi, S. Molendi +5
In intermediate-temperature (T = 2.5 - 4.5 keV) galaxy clusters, abundance measurements are almost-equally driven by Fe K and L transitions, at 6.7 keV and 0.9 - 1.3 keV, re…
Accretion processes in the galaxy cluster Hydra A/Abell 780
M. Girardi, W. Boschin, M. Nonino +2
Clusters of galaxies evolve and accrete mass, mostly from small galaxy systems. Our aim is to study the velocity field of the galaxy cluster Abell 780, which is known for the power…

I. Bartalucci, F. Gastaldello, E. Piconcelli +6
We present the characterisation of the massive cluster ClG-J at performed using a serendipitous XMM-Newton observation. High redshift and massive objects…
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…
Measuring the dynamical state of Planck SZ-selected clusters: X-ray peak - BCG offset
M. Rossetti, F. Gastaldello, G. Ferioli +6
We want to characterize the dynamical state of galaxy clusters detected with the Sunyaev-Zeldovich (SZ) effect by Planck and compare them with the dynamical state of clusters selec…
