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…
