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…

Astrometric Apparent Motion of High-redshift Radio Sources
Oleg Titov, Sandor Frey, Alexei Melnikov +10
Radio-loud quasars at high redshift (z > 4) are rare objects in the Universe and rarely observed with Very Long Baseline Interferometry (VLBI). But some of them have flux density s…

J2102+6015: an Intriguing Radio-loud Active Galactic Nucleus in the Early Universe
S. Frey, T. An, K. Gabányi +10
The powerful high-redshift quasar J2102+6015 (at z=4.575) may provide useful information for studying supermassive black hole growth, galaxy evolution and feedback in the early Uni…
