SuperModel Predictions in the Outskirts of the Galaxy Cluster Zwicky 3146
Roberto Fusco-Femiano
The relaxed galaxy cluster Zwicky 3146 is analyzed via the SuperModel, a tool already tested on many clusters since 2009. In particular, this analysis is focused on the intracluste…
Results from the SuperModel Analysis of the X-COP Galaxy Clusters Sample

In this work, the analysis of the stacked projected temperature profile of twelve galaxy clusters of the X-COP sample is performed via the SuperModel, a tool for investigating the…
Nonthermal Pressure in the Outskirts of Abell 2142
R. Fusco-Femiano, A. Lapi
Clumping and turbulence are expected to affect the matter accreted onto the outskirts of galaxy clusters. To determine their impact on the thermodynamic properties of Abell 2142 we…
The Intragroup versus the Intracluster Medium
A. Cavaliere, R. Fusco-Femiano, A. Lapi
Galaxy groups differ from clusters primarily by way of their lower masses, M~10^14 M_sun vs. M~10^15 M_sun. We discuss how mass affects the thermal state of the intracluster or the…
SuperModel Analysis of Abell 1246 and J255: on the Evolution of Galaxy Clusters from High to Low Entropy States
R. Fusco-Femiano, A. Lapi
We present an analysis of high-quality X-ray data out to the virial radius for the two galaxy clusters Abell 1246 and GMBCG J255.34805+64.23661 (J255) by means of our entropy-based…
Entropy Flattening, Gas Clumping and Turbulence in Galaxy Clusters
R. Fusco-Femiano, A. Lapi
Several physical processes and formation events are expected in cluster outskirts, a vast region up to now essentially not covered by observations. The recent Suzaku (X-ray) and Pl…
Turbulence in the SuperModel: Mass Reconstruction with Nonthermal Pressure for Abell 1835
R. Fusco-Femiano, A. Lapi
The total mass derived from X-ray emission is biased low in a large number of clusters when compared with the mass estimated via strong and weak lensing. Suzaku and Chandra observa…
The Planck Sunyaev-Zel'dovich vs. the X-ray View of the Coma Cluster
R. Fusco-Femiano, A. Lapi, A. Cavaliere
The Planck collaboration has recently published precise and resolved measurements of the Sunyaev-Zel'dovich effect in Abell 1656 (the Coma cluster of galaxies), so directly gauging…
A Grand Design for Galaxy Clusters: Connections and Predictions
A. Cavaliere, A. Lapi, R. Fusco-Femiano
We take up from a library of 12 galaxy clusters featuring extended X-ray observations of their Intra Cluster Plasma (ICP), analyzed with our entropy-based Supermodel. Its few intri…
Supermodel Analysis of the Hard X-Ray Excess in the Coma Cluster
Roberto Fusco-Femiano, Mauro Orlandini, Massimiliano Bonamente +1
The Supermodel provides an accurate description of the thermal contribution by the hot intracluster plasma which is crucial for the analysis of the hard excess. In this paper the t…
Non Thermal Support for the Outer Intracluster Medium
A. Cavaliere, A. Lapi, R. Fusco-Femiano
We submit that non thermalized support for the outer intracluster medium in relaxed galaxy clusters is provided by turbulence, driven by inflows of intergalactic gas across the vir…
Probing the Astrophysics of Cluster Outskirts
A. Lapi, R. Fusco-Femiano, A. Cavaliere
In galaxy clusters the entropy distribution of the IntraCluster Plasma modulates the latter's equilibrium within the Dark Matter gravitational wells, as rendered by our Supermodel.…
Galaxy Clusters, a Novel Look at Diffuse Baryons Withstanding Dark Matter Gravity
A. Cavaliere, A. Lapi, R. Fusco-Femiano
[abridged] The equilibria of the intracluster plasma (ICP) and of the gravitationally dominant dark matter (DM) are governed by the hydrostatic and the Jeans equation. Jeans, with…
