Radio-loudness statistics of quasars from Quaia-VLASS
Nestor Arsenov, Sandor Frey, András Kovács +1
Quasars are objects of high interest in extragalactic astrophysics, cosmology, and astrometry. One of their useful qualities is their potential radio loudness. However, the fractio…
Planetary radio interferometry and Doppler experiment as an operational component of the Jupiter Icy Moons Explorer mission
Vidhya Pallichadath, Dominic Dirkx, Marie S. Fayolle +9
We present an overview of the operations and engineering interface for Planetary Radio Interferometry and Doppler Experiment (PRIDE) radio astronomy observations as a scientific co…
Revealing faint compact radio jets at redshifts above 5 with very long baseline interferometry
Máté Krezinger, Giovanni Baldini, Marcello Giroletti +6
Over the past two decades, our knowledge of the high-redshift (z > 5) radio quasars has expanded, thanks to dedicated high-resolution very long baseline interferometry (VLBI) obser…
Revisiting a Core-Jet Laboratory at High Redshift: Analysis of the Radio Jet in the Quasar PKS 2215+020 at z=3.572
Sándor Frey, Judit Fogasy, Krisztina Perger +4
The prominent radio quasar PKS 2215+020 (J2217+0220) was once labelled as a new laboratory for core--jet physics at redshift z=3.572 because of its exceptionally extended jet struc…
Superluminal Motion and Jet Parameters in the Gamma-ray-Emitting Narrow-Line Seyfert 1 Galaxy TXS 1206+549
Bettina Kozák, Sándor Frey, Krisztina Éva Gabányi
Narrow-line Seyfert 1 (NLS1) galaxies are a peculiar subclass of active galactic nuclei (AGN). Among them, TXS 1206+549 belongs to a small group of radio-loud and gamma-ray-emittin…
Proper motion of the radio jets in two blazars at redshift above 3
Mate Krezinger, Sandor Frey, Krisztina Perger +7
There is still a limited number of high-redshift () active galactic nuclei (AGN) whose jet kinematics have been studied with very long baseline interferometry (VLBI). Without…
