Cosmic Duets II. Growth and accretion in Gaia Multi-Peak dual AGN at Cosmic Noon
M. Scialpi, F. Mannucci, D. Izquierdo-Villalba +36
We present the first statistical characterization of the physical properties of Cosmic Duets: dual AGN in the redshift range 0.5 z 3.0 with projected separations of 1…
A new era for Dual AGN science with SHARP
P. Severgnini, C. Vignali, A. De Rosa +21
The search for and the characterization of ultra-compact dual active galactic nuclei (AGN) are among the hottest topics of current extragalactic astrophysics. These systems involve…
Enhanced activity in close dual-AGN systems in the local Universe
Lorenzo Battistini, Alessandra De Rosa, Paola Severgnini +16
We present the study of an X-ray selected sample of active galactic nuclei (AGN) in pairs at projected spatial separations 1 </kpc < 100 at z < 0.1, using XMM-Newton and Chan…
Searching for unresolved massive black hole pairs through AGN photometric variability
Lorenzo Bertassi, Maria Charisi, Fabio Rigamonti +2
Since their discovery, AGN light curves are known to be intrinsically variable. In the optical/UV band, this variability is consistent with correlated or red noise and is particula…
The Advanced X-ray Imaging Satellite (AXIS) Community Science Book
Michael Koss, Nafisa Aftab, Steven W. Allen +395
The AXIS Community Science Book represents the collective effort of 592 scientists worldwide to define the transformative science enabled by the Advanced X-ray Imaging Satellite (A…
X-ray investigation of possible super-Eddington accretion in a radio-loud quasar at
L. Ighina, A. Caccianiga, T. Connor +19
We present radio and X-ray observations of the recently discovered radio-powerful quasar RACS J032021.44352104.1 using uGMRT, ATCA, LBA, and Chandra. The observed radio…
High- radio Quasars in RACS I: Selection, identification, and multi-wavelength properties
L. Ighina, A. Caccianiga, A. Moretti +21
Radio-bright, jetted quasars at serve as unique laboratories for studying supermassive black hole activity in the early Universe. In this work, we present a sample of high-$z…
The time evolution of the ultraviolet habitable zone
R. Spinelli, F. Borsa, G. Ghirlanda +3
For stars hosting Circumstellar Habitable Zone (CHZ) exoplanets, we investigate the time-evolution of their ultraviolet habitable zone (UHZ), the annular region around a star where…
Multi-wavelength properties of three new radio-powerful quasi-stellar objects discovered from RACS
L. Ighina, A. Caccianiga, A. Moretti +12
We present a multi-wavelength study of three new quasi-stellar objects (QSOs) identified from dedicated spectroscopic observations. The three sources were selected as hi…
Comprehensive view on a radio-loud QSO: from the radio to the optical/NIR to the X-ray band
Luca Ighina, Alessandro Caccianiga, Alberto Moretti +9
We present a multi-wavelength analysis, from the radio to the X-ray band, of the redshift VIK J231831 radio-loud (RL) quasi stellar object (QSO), one of the most distan…
