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…
Hitomi constraints on the 3.5 keV line in the Perseus galaxy cluster
Hitomi Collaboration, Felix A. Aharonian, Hiroki Akamatsu +215
High-resolution X-ray spectroscopy with Hitomi was expected to resolve the origin of the faint unidentified E=3.5 keV emission line reported in several low-resolution studies of va…
The black hole binary V404 Cygni: an obscured AGN analogue
S. E. Motta, J. J. E. Kajava, C. Sánchez-Fernández +2
Typical black hole binaries in outburst show spectral states and transitions, characterized by a clear connection between the inflow onto the black hole and outflow from its vicini…
XMM-Newton reveals a Seyfert-like X-ray spectrum in the z=3.6 QSO B1422+231
M. Dadina, C. Vignali, M. Cappi +5
Matter flows in the central regions of quasars during their active phases are probably responsible for the properties of the super-massive black holes and that of the bulges of hos…
The Wide-Angle Outflow of the Lensed z = 1.51 AGN HS 0810+2554
G. Chartas, M. Cappi, F. Hamann +4
We present results from X-ray observations of the gravitationally lensed z = 1.51 AGN HS 0810+2554 performed with the Chandra X-ray Observatory and XMM-Newton. Blueshifted absorpti…
