Recovering true metal abundances of the ICM [PDF]

open access: yesarXiv, 2001
Recovering the true average abundance of the intracluster medium (ICM) is crucial for estimates of its global metal content, which in turn is linked to its past evolution and to the star formation history of the stellar component of the cluster. We analyze here how the presence of abundance gradients affects commonly adopted estimates of the average ...

Viscosity in cosmological simulations of clusters of galaxies [PDF]

open access: yesarXiv, 2005
The physics of the intracluster medium, in particular the values for the thermal conductivity and the viscosity are largely unknown and subject to an ongoing debate. Here, we study the effect of viscosity on the thermal state of the intracluster medium using three-dimensional cosmological simulations of structure formation.

Density Fluctuations in the Intracluster Medium: An Attempt to Constrain Viscosity with Cosmological Simulations

open access: yesThe Astrophysical Journal
The impact of viscosity in the intracluster medium (ICM) is still an open question in astrophysics. To address this problem, we have run a set of cosmological simulations of three galaxy clusters with a mass larger than M _Vir > 10 ^15 M _⊙ at z = 0 ...

The NuSTAR View of Perseus: The Intracluster Medium and a Peculiar Hard Excess

open access: yesThe Astrophysical Journal
As the brightest galaxy cluster in the X-ray sky, Perseus is an excellent target for studying the intracluster medium (ICM), but until recently, its active galactic nucleus (AGN) made studies of the diffuse emission near its center nearly impossible to ...
