Directly tracking the re-brightening of a supermassive black hole accretion disk
R. Middei, E. Nardini, C. Done +12
Accretion onto supermassive black holes powers the most luminous persistent sources in the Universe, the so-called active galactic nuclei, whose emission is characterized by two di…

Investigating the interplay between the coronal properties and the hard X-ray variability of active galactic nuclei with NuSTAR
Roberto Serafinelli, Alessandra De Rosa, Alessia Tortosa +11
Active galactic nuclei (AGN) are extremely variable in the X-ray band down to very short timescales. However, the driver behind the X-ray variability is still poorly understood. Pr…

Investigating the nuclear properties of highly accreting active galactic nuclei with XMM-Newton
M. Laurenti, F. Tombesi, F. Vagnetti +7
Our understanding of highly accreting AGNs is hampered by the lack of a complete systematic investigation in terms of their main spectral and variability properties, and by the rel…
