Nitrogen abundance in the X-ray halos of clusters and groups of galaxies
Junjie Mao, J. de Plaa, J. S. Kaastra +6
Chemical abundances in the X-ray halos (also known as the intracluster medium, ICM) of clusters and groups of galaxies can be measured via prominent emission line features in their…
Radial metal abundance profiles in the intra-cluster medium of cool-core galaxy clusters, groups, and ellipticals
François Mernier, Jelle de Plaa, Jelle S. Kaastra +10
The hot intra-cluster medium (ICM) permeating galaxy clusters and groups is not pristine, as it is continuously enriched by metals synthesised in Type Ia (SNIa) and core-collapse (…
Insights into the location and dynamics of the coolest X-ray emitting gas in clusters of galaxies
Ciro Pinto, Andrew C. Fabian, Anna Ogorzalek +10
We extend our previous study of the cool gas responsible for the emission of OVII X-ray lines in the cores of clusters and groups of galaxies. This is the coolest X-ray emitting ph…
Chemical Enrichment RGS cluster sample (CHEERS): Constraints on turbulence
Ciro Pinto, Jeremy S. Sanders, Norbert Werner +6
Feedback from AGN, galactic mergers, and sloshing are thought to give rise to turbulence, which may prevent cooling in clusters. We aim to measure the turbulence in clusters of gal…
Abundance and temperature distributions in the hot intra-cluster gas of Abell 4059
François Mernier, Jelle de Plaa, Lorenzo Lovisari +5
Using the EPIC and RGS data from a deep (~200 ks) XMM-Newton observation, we investigate the temperature structure (kT and sigma_T ) and the abundances of 9 elements (O, Ne, Mg, Si…
Discovery of O VII line emitting gas in elliptical galaxies
Ciro Pinto, Andrew C. Fabian, Norbert Werner +7
In the cores of ellipticals, clusters, and groups of galaxies, the gas has a cooling time shorter than 1 Gyr. It is possible to probe cooling flows through the detection of Fe XVII…
