Absorption and scattering by interstellar dust in the silicon K-edge of GX 5-1
S. T. Zeegers, E. Costantini, C. P. de Vries +6
We study the absorption and scattering of X-ray radiation by interstellar dust particles, which allows us to access the physical and chemical properties of dust. The interstellar d…
Direct probe of the inner accretion flow around the supermassive black hole in NGC 2617
M. Giustini, E. Costantini, B. De Marco +12
NGC 2617 is a nearby () active galaxy that recently switched from being a Seyfert 1.8 to be a Seyfert 1.0. At the same time, it underwent a strong increase of X-ray flu…
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…
Multiwavelength campaign on Mrk 509 XV. A global modeling of the broad emission lines in the Optical, UV and X-ray bands
E. Costantini, G. Kriss, J. S. Kaastra +11
We model the broad emission lines present in the optical, UV and X-ray spectra of Mrk 509, a bright type 1 Seyfert galaxy. The broad lines were simultaneously observed during a lar…
