New Radio-Loud QSOs at the end of the Re-ionisation Epoch
L. Ighina, A. Caccianiga, A. Moretti +5
We present the selection of high-redshift () radio-loud (RL) quasi-stellar object (QSO) candidates from the combination of the radio Rapid ASKAP Continuum Survey (RACS…
Impact of the CMB on the evolution of AGNs and their relativisitc jets at the highest redshift
Luca Ighina
Radio-Loud (RL) Active Galactic Nuclei (AGNs) are among the brightest astrophysical sources at all wavelengths. Their relativistic jets can affect both their Supermassive Black Hol…
Constraining the Radio Properties of the =6.44 QSO VIK J23183113
Luca Ighina, James K. Leung, Jess W. Broderick +19
The recent detection of the quasi-stellar object (QSO) VIKING J231818.3311346 (hereafter VIK J23183113) at redshift in the Rapid ASKAP Continuum Survey (RACS) uncove…
The central engine of the highest redshift blazar
Silvia Belladitta, Alessandro Caccianiga, Alessandro Diana +8
We report on a LUCI/Large Binocular Telescope near-infrared (NIR) spectrum of PSO J030947.49+271757.31 (hereafter PSO J0309+27), the highest redshift blazar known to date (z6…
