Sound waves in the intracluster medium [PDF]
Monthly Notices of the Royal Astronomical Society, 2009 We present an analysis of the behaviour of a perturbed radio cocoon. Comparisons with observations of sound waves detected in the Perseus and Virgo clusters suggest the separations of observed ripples correspond to the natural oscillation frequency of the cocoon.

THE INTRAGROUP VERSUS THE INTRACLUSTER MEDIUM [PDF]
The Astrophysical Journal, 2016 ABSTRACT Galaxy groups differ from clusters primarily by way of their lower masses, M ∼ 1014 M ⊙ versus M ∼ 1015 M ⊙. We discuss how mass affects the thermal state of the intracluster or the intragroup medium, specifically as to their entropy levels and radial ...

Turbulence in the intracluster medium: simulations, observables, and thermodynamics [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 We conduct two kinds of homogeneous isotropic turbulence simulations relevant for the intracluster medium (ICM): (i) pure turbulence runs without radiative cooling; (ii) turbulent heating$+$radiative cooling runs with global thermal balance. For pure turbulence runs in the subsonic regime, the rms density and surface brightness (SB) fluctuations vary ...

Cosmological simulations of the intracluster medium [PDF]
Monthly Notices of the Royal Astronomical Society, 2004 We investigate the properties of the intracluster medium (ICM) that forms within N-body/hydrodynamical simulations of galaxy clusters in a \LambdaCDM cosmology. When radiative cooling and a simple model for galactic feedback are included, our clusters have X-ray luminosities and temperatures in good agreement with observed systems, demonstrating the ...

Introducing the TNG-Cluster simulation: Overview and the physical properties of the gaseous intracluster medium [PDF]
Astronomy & Astrophysics, 2023 We introduce the new TNG-Cluster project, an addition to the IllustrisTNG suite of cosmological magnetohydrodynamical simulations of galaxy formation.

Feeding and feedback processes in the Spiderweb proto-intracluster medium [PDF]
Astronomy & Astrophysics, 2023 We present a detailed analysis of the thermal, diffuse emission of the proto-intracluster medium (proto-ICM) detected in the halo of the Spiderweb Galaxy at $z=2.16,$ within a radius of sim 150 kpc. Our main goal is to derive the thermodynamic profiles

The complex interplay of AGN jet-inflated bubbles and the intracluster medium [PDF]
Monthly notices of the Royal Astronomical Society, 2022 We use SWIFT, a smoothed particle hydrodynamics code, to simulate the evolution of bubbles inflated by active galactic nuclei (AGN) jets, as well as their interactions with the ambient intracluster medium (ICM).

Populations of Magnetized Filaments in the Intracluster Medium and the Galactic Center [PDF]
Astrophysical Journal Letters, 2022 Magnetized radio filaments are found in abundance in the inner few hundred parsecs of our galaxy. Progress in understanding this population of filaments has been slow over the last few decades, in part due to a lack of detection elsewhere in the galaxy ...
