The Quiescent Intracluster Medium in the Core of the Perseus Cluster
Hitomi Collaboration, Felix Aharonian, Hiroki Akamatsu +213
Clusters of galaxies are the most massive gravitationally-bound objects in the Universe and are still forming. They are thus important probes of cosmological parameters and a host…
Highly ionized disc and transient outflows in the Seyfert galaxy IRAS 18325-5926
K. Iwasawa, A. C. Fabian, E. Kara +3
We report on strong X-ray variability and the Fe K band spectrum of the Seyfert galaxy IRAS 18325-5926 obtained from the 2001 XMM-Newton EPIC pn observation of a 120 ks duration. W…
The rhythm of Fairall 9 -- I: Observing the spectral variability with XMM-Newton and NuSTAR
Anne Lohfink, Christopher Reynolds, Ciro Pinto +13
We present a multi-epoch X-ray spectral analysis of the Seyfert 1 galaxy Fairall 9. Our analysis shows that Fairall 9 displays unique spectral variability in that its ratio residua…
