Simulating the transport of relativistic electrons and magnetic fields injected by radio galaxies in the intracluster medium [PDF]
Astronomy & Astrophysics, 2021 Radio galaxies play an important role in the seeding of cosmic rays and magnetic fields in galaxy clusters. Here, we simulate the evolution of relativistic electrons injected into the intracluster medium by radio galaxies.

Nonthermal support for the outer intracluster medium [PDF]
Astronomy & Astrophysics, 2010 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 virial accretion shocks. We expect this component to increase briskly during the cluster development for z<1/2, due to three factors.

Differential reddening in 48 globular clusters: An end to the quest for the intracluster medium [PDF]
Astronomy & AstrophysicsFor decades, it has been theorized that a tenuous but detectable intracluster medium should be present in globular clusters, which is continuously replenished by the gas and dust ejected by bright giants and periodically cleared by interactions with the ...

Life cycle of cosmic-ray electrons in the intracluster medium [PDF]
Astronomy & Astrophysics, 2022 We simulate the evolution of relativistic electrons injected into the medium of a small galaxy cluster by a central radio galaxy, studying how the initial jet power affects the dispersal and the emission properties of radio plasma.

Missing thermal energy of the intracluster medium [PDF]
Monthly Notices of the Royal Astronomical Society, 2007 The Sunyaev-Zel'dovich (SZ) effect is a direct probe of thermal energy content of the Universe, induced in the cosmic microwave background (CMB) sky through scattering of CMB photons off hot electrons in the intracluster medium (ICM). We report a 9-sigma detection of the SZ signal in the CMB maps of Wilkinson Microwave Anisotropy Probe (WMAP) 3yr data,

Enrichment of the Hot Intracluster Medium: Observations [PDF]
Space Science Reviews, 2018 Four decades ago, the firm detection of an Fe-K emission feature in the X-ray spectrum of the Perseus cluster revealed the presence of iron in its hot intracluster medium (ICM). With more advanced missions successfully launched over the last 20 years, this discovery has been extended to many other metals and to the hot atmospheres of many other galaxy ...

oMEGACat. VII. Tracing Interstellar and Intracluster Medium of ω Centauri Using Sodium Absorptions
The Astrophysical JournalWe investigate the foreground interstellar medium along the line of sight and intracluster medium of ω Centauri ( ω Cen) by measuring the equivalent width of Na I D absorptions from MUSE observations. The large line-of-sight velocity difference between ω

Quasar Feedback on the Intracluster Medium [PDF]
The Astrophysical Journal, 2002 Galaxy groups are quite underluminous in X-rays compared to clusters, so the intracluster medium (ICM) has to be considerably underdense in the former. We consider this to be due to substantial energy fed back into the ICM when the baryons in the member galaxies condense into stars ending up in supernovae (SNe) or accrete onto central supermassive ...
