A XRISM view of the iron line complex in NGC 1068: Rethinking the prototypical Compton-thick AGN
S. Bianchi, B. Vander Meulen, E. Bertola +32
We analyze a XRISM/Resolve observation of NGC1068, focusing on the Fe K and Fe K fluorescent lines and on the Fe XXV and Fe XXVI emission complexes. Line centroid energies, i…
A Song of Lines and Winds: Tracing the Signatures of AGN Outflows in X-rays
M. Laurenti, F. Tombesi, P. Condò +14
Ultra-fast outflows (UFOs) are highly ionized, mildly relativistic winds seen in the X-ray spectra of active galactic nuclei (AGN) and are thought to contribute to AGN feedback and…
The WISSH quasar project. XII. X-ray view of the most luminous quasi-stellar objects at Cosmic Noon
C. Degli Agosti, C. Vignali, E. Piconcelli +25
To improve our knowledge of nuclear emission in luminous QSOs at Cosmic Noon, we studied the X-ray emission of the WISE/SDSS-selected hyper-luminous (WISSH) QSO sample: 85 broad-li…
An Eddington Limited Accretion Disk Wind in the narrow line Seyfert 1, PG 1448+273
J. N. Reeves, V. Braito, A. Luminari +5
PG 1448+273 is a luminous, nearby (), narrow line Seyfert 1 galaxy, which likely accretes close to the Eddington limit. Previous X-ray observations of PG 1448 with XMM-Ne…
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…
HYPerluminous quasars at the Epoch of ReionizatION (HYPERION). A new regime for the X-ray nuclear properties of the first quasars
L. Zappacosta, E. Piconcelli, F. Fiore +40
The existence of luminous quasars (QSO) at the Epoch of Reionization (EoR; i.e. z>6) powered by supermassive black holes (SMBH) with masses challenges models…
X-HESS: a large sample of highly accreting serendipitous AGN under the XMM-Newton microscope
M. Laurenti, F. Tombesi, F. Vagnetti +3
The bulk of X-ray spectroscopic studies of active galactic nuclei (AGN) are focused on local () sources with low-to-moderate () Eddington ratio ().…
X-ray spectroscopic survey of highly-accreting AGN
M. Laurenti, E. Piconcelli, L. Zappacosta +14
Improving our understanding of the nuclear properties of high-Eddington ratio () active galactic nuclei (AGN) is necessary since the bulk of X-ray spectroscopic stu…
Location and energetics of the ultra-fast outflow in PG 1448+273
M. Laurenti, A. Luminari, F. Tombesi +3
Ultra-fast outflows (UFOs) play a key role in the AGN feedback mechanism. It is therefore important to fully characterize their location and energetics. We study the UFO in the lat…
Individual optical variability of Active Galactic Nuclei from the MEXSAS2 sample
M. Laurenti, F. Vagnetti, R. Middei +1
Most of the variability studies of active galactic nuclei (AGNs) are based on ensemble analyses. Nevertheless, it is interesting to provide estimates of the individual variability…
