Photoionized emission and absorption features in the high-resolution X-ray spectra of NGC 3783

Junjie Mao, M. Mehdipour, J. S. Kaastra +14

Our Swift monitoring program triggered two joint XMM-Newton, NuSTAR and HST observations on 11 and 21 December 2016 targeting NGC 3783, as its soft X-ray continuum was heavily obsc…

HST/COS observations of the newly discovered obscuring outflow in NGC 3783

G. A. Kriss, M. Mehdipour, J. S. Kaastra +24

To understand the nature of transient obscuring outflows in active galactic nuclei, we observed the Seyfert 1 galaxy NGC 3783 on two occasions in December 2016 triggered by Swift m…

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…

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-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…
