Pressure of the hot gas in simulations of galaxy clusters
S. Planelles, D. Fabjan, S. Borgani +11
We analyze the radial pressure profiles, the ICM clumping factor and the Sunyaev-Zel'dovich (SZ) scaling relations of a sample of simulated galaxy clusters and groups identified in…
Spectral Energy Distribution Mapping of Two Elliptical Galaxies on sub-kpc scales
Alexandre Amblard, Pasquale Temi, Massimo Gaspari +1
We use high-resolution Herschel-PACS data of 2 nearby elliptical galaxies, IC1459 & NGC2768 to characterize their dust and stellar content. IC1459 & NGC2768 have an unusually large…
Testing the Large-Scale Environments of Cool-core and Noncool-core Clusters with Clustering Bias
Elinor Medezinski, Nicholas Battaglia, Jean Coupon +4
There are well-observed differences between cool-core (CC) and non-cool-core (NCC) clusters, but the origin of this distinction is still largely unknown. Competing theories can be…
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…
Raining on black holes and massive galaxies: the top-down multiphase condensation model
M. Gaspari, P. Temi, F. Brighenti
The atmospheres filling massive galaxies, groups, and clusters display remarkable similarities with rainfalls. Such plasma halos are shaped by AGN heating and subsonic turbulence (…
Cosmological hydrodynamical simulations of galaxy clusters: X-ray scaling relations and their evolution
N. Truong, E. Rasia, P. Mazzotta +11
We analyse cosmological hydrodynamical simulations of galaxy clusters to study the X-ray scaling relations between total masses and observable quantities such as X-ray luminosity,…
7.1 keV sterile neutrino constraints from X-ray observations of 33 clusters of galaxies with Chandra ACIS
F. Hofmann, J. S. Sanders, K. Nandra +2
Recently an unidentified emission line at 3.55 keV has been detected in X-ray spectra of clusters of galaxies. The line has been discussed as a possible decay signature of 7.1 keV…
Kinetic AGN Feedback Effects on Cluster Cool Cores Simulated using SPH
Paramita Barai, Giuseppe Murante, Stefano Borgani +4
We implement novel numerical models of AGN feedback in the SPH code GADGET-3, where the energy from a supermassive black hole (BH) is coupled to the surrounding gas in the kinetic…
On the nature of hydrostatic equilibrium in galaxy clusters
V. Biffi, S. Borgani, G. Murante +7
In this paper we investigate the level of hydrostatic equilibrium (HE) in the intra-cluster medium of simulated galaxy clusters, extracted from state-of-the-art cosmological hydrod…
Thermal SZ fluctuations in the ICM: probing turbulence and thermodynamics in Coma cluster with
Rishi Khatri, Massimo Gaspari
We report the detection of thermal Sunyaev-Zeldovich effect (SZ) fluctuations in the intracluster medium (ICM) of Coma cluster observed with . The SZ data links the m…
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…
