The missing FeII bump in faint JWST AGN: possible evidence for metal-poor broad-line regions at early cosmic times
Bartolomeo Trefoloni, Xihan Ji, Roberto Maiolino +6
Recent JWST observations have revealed a large population of intermediate/low-luminosity AGN at early times with peculiar properties, different from local AGN or luminous quasars.…
The WISSH quasars project VII. The impact of extreme radiative field in the accretion disk and X-ray corona interplay
L. Zappacosta, E. Piconcelli, M. Giustini +14
Hyperluminous quasars ( erg s) are ideal laboratories to study the interaction and impact of extreme radiative field and the most powerful winds…
The WISSH quasars project V. ALMA reveals the assembly of a giant galaxy around a z=4.4 hyper-luminous QSO
M. Bischetti, E. Piconcelli, C. Feruglio +11
We present an ALMA high-resolution observation of the 840 um continuum and [CII] line emission in the WISE-SDSS selected hyper-luminous (WISSH) QSO J1015+0020 at z~4.4. Our analysi…
The WISSH Quasars Project IV. BLR versus kpc-scale winds
G. Vietri, E. Piconcelli, M. Bischetti +21
We have undertaken a multi-band observing program aimed at obtaining a complete census of winds in a sample of WISE/SDSS selected hyper-luminous (WISSH) QSOs at z~2-4. We have anal…
The WISSH Quasars Project III. X-ray properties of hyper-luminous quasars
S. Martocchia, E. Piconcelli, L. Zappacosta +14
We perform a survey of the X-ray properties of 41 objects from the WISE/SDSS selected Hyper-luminous (WISSH) quasars sample, composed by 86 broad-line quasars (QSOs) with bolometri…
On the observed distributions of black hole masses and Eddington ratios from radiation pressure corrected virial indicators
A. Marconi, D. Axon, R. Maiolino +5
The application of the virial theorem to the Broad Line Region of Active Galactic Nuclei allows Black Hole mass estimates for large samples of objects at all redshifts. In a recent…
