Compact and variable radio emission from an active galaxy with supersoft X-ray emission
Lei Yang, Xinwen Shu, Fabao Zhang +15
RX J1301.9+2747 is a unique active galaxy with supersoft X-ray spectrum that lacks significant emission at energies above 2 keV. In addition, it is one of few galaxies displaying q…
Multiphase Powerful Outflows Detected in High-z Quasars
George Chartas, Massimo Cappi, Cristian Vignali +7
We present results from a comprehensive study of ultrafast outflows (UFOs) detected in a sample of fourteen quasars, twelve of which are gravitationally lensed, in a redshift range…
On Synthetic Absorption Line Profiles of Thermally Driven Winds from Active Galactic Nuclei
Shalini Ganguly, Daniel Proga, Tim Waters +7
The warm absorbers observed in more than half of all nearby active galactic nuclei (AGN) are tracers of ionized outflows located at parsec scale distances from the central engine.…
The Quest for Dual and Binary Supermassive Black Holes: A Multi-Messenger View
Alessandra De Rosa, Cristian Vignali, Tamara Bogdanović +27
The quest for binary and dual supermassive black holes (SMBHs) at the dawn of the multi-messenger era is compelling. Detecting dual active galactic nuclei (AGN) -- active SMBHs at…
A global view of the inner accretion and ejection flow around super massive black holes: radiation driven accretion disk winds in a physical context
Margherita Giustini, Daniel Proga
Understanding the physics and geometry of accretion and ejection around super massive black holes (SMBHs) is important to understand the evolution of active galactic nuclei (AGN) a…
The variability of the warm absorber in I Zwicky 1 as seen by XMM-Newton
C. V. Silva, E. Costantini, M. Giustini +4
We present new XMM-Newton observations of the intriguing warm absorber in I Zwicky 1. This luminous and nearby narrow-line Seyfert 1 galaxy shows ionized absorption by two componen…
The rest-frame UV-to-optical spectroscopy of APM 08279+5255 - BAL classification and black hole mass estimates
F. G. Saturni, M. Bischetti, E. Piconcelli +9
We present the analysis of the rest-frame optical-to-UV spectrum of APM 08279+5255, a well-known lensed broad absorption line (BAL) quasar at . The spectroscopic data ar…
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…
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…
