A central drop of ICM Fe abundance has been observed in several cool-core clusters. It has been proposed that this abundance drop may be due, at least partially, to the depletion of Fe into dust grains in the central, high-density regions. According to this scenario, noble gas elements such as Ar and Ne are not expected to be depleted into dust, and therefore should not show any drop, but follow the general increase of metal abundance toward the center. In this work, we test this scenario by… Expand

Constraining the origin and models of chemical enrichment in galaxy clusters using the Athena X-IFU
The chemical enrichment of the Universe at all scales is related to stellar winds and explosive supernovae phenomena. Metals produced by stars and later spread at the mega-parsec scale through theExpand
The chemical evolution of galaxy clusters: Dissecting the iron mass budget of the intracluster medium
We study the chemical evolution of galaxy clusters by measuring the iron mass in the ICM after dissecting the abundance profiles into different components. We use Chandra archival observations of 186Expand


A volume-limited sample of X-ray galaxy groups and clusters – III. Central abundance drops
We present the results of a search and study of central abundance drops in a volume-limited sample (z<=0.071) of 101 X-ray galaxy groups and clusters. These are best observed in nearby, and so bestExpand
Possible depletion of metals into dust grains in the core of the Centaurus cluster of galaxies
We present azimuthally averaged metal abundance profiles from a full, comprehensive, and conservative re-analysis of the deep (similar to 800 ks total net exposure) Chandra/ACIS-S observation of theExpand
Radial metal abundance profiles in the intra-cluster medium of cool-core galaxy clusters, groups, and ellipticals
The hot intra-cluster medium (ICM) permeating galaxy clusters and groups is not pristine, as it has been continuously enriched by metals synthesised in Type Ia (SNIa) and core-collapse (SNcc)Expand
Searching for the missing iron mass in the core of the Centaurus cluster
We re-analyse a combined 198 ks Chandra observation of NGC4696, the brightest galaxy of the Centaurus cluster. We extract temperature and metallicity profiles from the data, and we confirm theExpand
