Hot atmospheres of galaxies, groups, and clusters of galaxies
Norbert Werner, François Mernier
Most of the ordinary matter in the local Universe has not been converted into stars but resides in a largely unexplored diffuse, hot, X-ray emitting plasma. It pervades the gravita…
Iron abundance distribution in the hot gas of merging galaxy clusters
I. Urdampilleta, F. Mernier, J. S. Kaastra +4
We present XMM-Newton/EPIC observations of six merging galaxy clusters and study the distributions of their temperature, iron (Fe) abundance and pseudo-entropy along the merging ax…
Possible depletion of metals into dust grains in the core of the Centaurus cluster of galaxies
K. Lakhchaura, F. Mernier, N. Werner
We present azimuthally averaged metal abundance profiles from a full, comprehensive, and conservative re-analysis of the deep (800 ks total net exposure) \textit{Chandra}/ACI…
Solar chemical composition in the hot gas of cool-core ellipticals, groups, and clusters of galaxies
François Mernier, Norbert Werner, Jelle de Plaa +6
The hot intracluster medium (ICM) pervading galaxy clusters and groups is rich in metals, which were synthesised by billions of supernovae and have accumulated in cluster gravitati…
Mass-Metallicity Relation from Cosmological Hydrodynamical Simulations and X-ray Observations of Galaxy Groups and Clusters
Nhut Truong, Elena Rasia, Veronica Biffi +7
Recent X-ray observations of galaxy clusters show that the distribution of intra-cluster medium (ICM) metallicity is remarkably uniform in space and time. In this paper, we analyse…
Mass-invariance of the iron enrichment in the hot haloes of massive ellipticals, groups, and clusters of galaxies
François Mernier, Jelle de Plaa, Norbert Werner +7
X-ray measurements find systematically lower Fe abundances in the X-ray emitting haloes pervading groups ( keV) than in clusters of galaxies. These results have been…
