An X-ray Significantly Variable, Luminous, Type 2 Quasar at z = 2.99 with a Massive Host Galaxy
Xiurui Zhao, Stefano Marchesi, Marco Ajello +8
We present a comprehensive X-ray analysis and spectral energy distribution (SED) fitting of WISEA J171419.96+602724.6, an extremely luminous type 2 quasar at = 2.99. The source…
KASHz+SUPER: Evidence of cold molecular gas depletion in AGN hosts at cosmic noon
E. Bertola, C. Circosta, M. Ginolfi +32
The energy released by AGN has the potential to heat or remove the gas of the ISM, thus likely impacting the cold molecular gas reservoir of host galaxies at first, with star forma…
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…
Fast SMBH growth in the SPT2349--56 protocluster at
Fabio Vito, William N. Brandt, Andrea Comastri +7
Protoclusters at are gas-rich regions characterized by high star-formation activity. The same physical properties that enhance star formation in protoclusters are also though…
The XMM-Newton and NuSTAR view of IRASF11119+3257. I Detection of multiple UFO components and a very cold corona
G. Lanzuisi, G. Matzeu, P. Baldini +21
IRASF11119 is an ultra-luminous IR galaxy with post-merger morphology, hosting a type-1 QSO at z=0.189. Its 2013 Suzaku spectrum shows a prominent Ultra Fast Outflow (UFO) absorpti…
Feeding Hidden Monsters: a Super-Eddington accreting Black Hole ~1.5 Gyr after the Big Bang
Hyewon Suh, Julia Scharwächter, Emanuele Paolo Farina +13
Recent James Webb Space Telescope (JWST) observations have revealed a surprisingly abundant population of faint, dusty active galactic nuclei (AGNs) at z~4-7. Together with the pre…
Supermassive Black Hole Winds in X-rays -- SUBWAYS. III. A population study on ultra-fast outflows
V. E. Gianolli, S. Bianchi, P-O Petrucci +44
The detection of blue-shifted absorption lines likely associated with ionized Iron K-shell transitions in the X-ray spectra of many Active Galactic Nuclei (AGN) suggests the presen…
Winds of change: the nuclear and galaxy-scale outflows and the X-ray variability of 2MASS 0918+2117
P. Baldini, G. Lanzuisi, M. Brusa +21
Powerful outflows from active galactic nuclei (AGN) can significantly impact the gas reservoirs of their host galaxies. However, it is still unclear how these outflows can propagat…
Heavily Obscured AGN detection: a Radio vs X-ray challenge
Giovanni Mazzolari, Roberto Gilli, Marcella Brusa +11
In this work, we study the AGN radio detection effectiveness in the major deep extragalactic surveys, considering different AGN obscuration levels, redshift, and AGN bolometric lum…
