The first broadband X-ray view of the narrow line Seyfert 1 Ton S180
G. A. Matzeu, E. Nardini, M. L. Parker +15
We present joint \textit{XMM-Newton} and \textit{NuSTAR} observations of the `bare' narrow line Seyfert 1 Ton S180 (), carried out in 2016 and providing the first hard X-r…
Rapid late-time X-ray brightening of the tidal disruption event OGLE16aaa
Jari J. E. Kajava, Margherita Giustini, Richard D. Saxton +1
Stars that pass too close to a super-massive black hole may be disrupted by strong tidal forces. OGLE16aaa is one such tidal disruption event (TDE) which rapidly brightened and pea…
X-raying winds in distant quasars: the first high-redshift wind duty cycle
E. Bertola, M. Dadina, M. Cappi +6
Theoretical models of wind-driven feedback from Active Galactic Nuclei (AGN) often identify Ultra-fast outflows (UFOs) as being the main cause for generating galaxy-size outflows,…
X-ray quasi-periodic eruptions from the galactic nucleus of RX J1301.9+2747
Margherita Giustini, Giovanni Miniutti, Richard D. Saxton
Following the recent discovery of X-ray quasi-periodic eruptions (QPEs) coming from the nucleus of the galaxy GSN 069, here we report on the detection of QPEs in the active galaxy…
The role of failed accretion disk winds in active galactic nuclei
Margherita Giustini, Daniel Proga
Both observational and theoretical evidence point at outflows originating from accretion disks as fundamental ingredients of active galactic nuclei (AGN). These outflows can have m…
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…
