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…
A powerful (and likely young) radio-loud quasar at z=5.3
S. Belladitta, A. Moretti, A. Caccianiga +5
We present the discovery of PSO J191.0569686.43172 (hereafter PSO J19186), a new powerful radio-loud quasar (QSO) in the early Universe (z = 5.32). We discovered it by cross-…
Multi-scale VLBI observations of the candidate host galaxy of GRB 200716C
S. Giarratana, M. Giroletti, C. Spingola +3
We present the discovery and the subsequent follow up of radio emission from SDSS J130402.36293840.6 (J1304+2938), the candidate host galaxy of the gamma-ray burst GRB~200716C.…
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…
