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…
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…
