The radio properties of the JWST-discovered AGN
G. Mazzolari, R. Gilli, R. Maiolino +23
We explore the radio emission of JWST-selected Broad Line AGN (BLAGN, or type 1) in the GOODS-N field. We use deep radio data at different frequencies (144\,MHz, 1.5\,GHz, 3\,GHz,…
The host galaxies of radio-loud quasars at z>5 with ALMA
C. Mazzucchelli, R. Decarli, S. Belladitta +13
The interaction between radio-jets and quasar host galaxies plays a paramount role in quasar/galaxy co-evolution. However, very little has been known so far about this interaction…
A blazar in the epoch of reionization
Eduardo Banados, Emmanuel Momjian, Thomas Connor +21
Relativistic jets are thought to play a crucial role in the formation and evolution of massive galaxies and supermassive black holes. Blazars, which are quasars with jets aligned a…
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…
Optical and near-infrared spectroscopy of quasars at : public data release and composite spectrum
Silvia Onorato, Joseph F. Hennawi, Jan-Torge Schindler +18
We present optical and near-infrared (NIR) spectroscopic observations for a sample of quasars at with absolute magnitudes at Å in the range $-28.82…
The SRG/eROSITA All-Sky Survey: X-ray beacons at late cosmic dawn
J. Wolf, M. Salvato, S. Belladitta +12
The SRG/eROSITA All-Sky Survey (eRASS) is expected to contain ~100 quasars that emitted their light when the universe was less than a billion years old, i.e. at z>5.6. By selection…
Euclid: ERO -- NISP-only sources and the search for luminous galaxies
J. R. Weaver, S. Taamoli, C. J. R. McPartland +185
This paper presents a search for high redshift galaxies from the Euclid Early Release Observations program "Magnifying Lens." The 1.5 deg area covered by the twin Abell lensing…
Euclid: Early Release Observations -- A preview of the Euclid era through a galaxy cluster magnifying lens
H. Atek, R. Gavazzi, J. R. Weaver +200
We present the first analysis of the Euclid Early Release Observations (ERO) program that targets fields around two lensing clusters, Abell 2390 and Abell 2764. We use VIS and NISP…
Euclid: Early Release Observations -- Programme overview and pipeline for compact- and diffuse-emission photometry
J. -C. Cuillandre, E. Bertin, M. Bolzonella +260
The Euclid ERO showcase Euclid's capabilities in advance of its main mission, targeting 17 astronomical objects, from galaxy clusters, nearby galaxies, globular clusters, to star-f…
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…
Quasar Island -- Three new quasars, including a lensed candidate, identified with contrastive learning
Xander Byrne, Romain A. Meyer, Emanuele Paolo Farina +5
Of the hundreds of quasars discovered to date, only one is known to be gravitationally lensed, despite the high lensing optical depth expected at . High-reds…
Obscuration in high redshift jetted QSO
A. Caccianiga, L. Ighina, A. Moretti +6
Obscuration in high-redshift quasi-stellar objects (QSO) has a profound impact on our understanding of the evolution of supermassive black holes across the cosmic time. An accurate…
Recognizing Blazars Using Radio Morphology from the VLA Sky Survey
Zhang-Liang Xie, Eduardo Banados, Silvia Belladitta +4
Blazars are radio-loud Active Galactic Nuclei (AGN) whose jets have a very small angle to our line of sight. Observationally, the radio emission are mostly compact or a compact-cor…
