From compact jets to extended lobes: radio morphologies of distant quasars at z > 4
K. É. Gabányi, M. Kunert-Bajraszewska, A. Krauze +9
High-redshift quasars play an essential role in studying the growth and evolution of supermassive black holes and active galactic nuclei (AGN). Radio-loud quasars additionally enab…
VLBI observations of the high-redshift X-ray bright blazar SRGE J170245.3+130104
Yuanqi Liu, Tao An, Shaoguang Guo +8
Aims. The X-ray luminous and radio-loud AGN SRGE J170245.3+130104 discovered at z 5.5 provides unique chances to probe the SMBH growth and evolution with powerful jets in th…
European VLBI Network observations of the peculiar radio source 4C 35.06 overlapping with a compact group of nine galaxies
Patrik Milán Veres, Krisztina Éva Gabányi, Sándor Frey +8
Context. According to the hierarchical structure formation model, brightest cluster galaxies (BCGs) evolve into the most luminous and massive galaxies in the Universe through multi…
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…
Milliarcsecond-scale radio structure of the most distant BL Lac object candidate at redshift 6.57
S. Frey, Y. Zhang, K. Perger +7
The existence of accreting supermassive black holes up to billions of solar masses at early cosmological epochs (in the context of this work, redshifts z>=6) requires very fast gro…
VLBI Observations of a sample of Palomar-Green quasars II: characterising the parsec-scale radio emission
Ailing Wang, Tao An, Yingkang Zhang +4
This study uses multi-frequency Very Long Baseline Interferometry (VLBI) to study the radio emission from 10 radio-quiet quasars (RQQs) and four radio-loud quasars (RLQs). The dive…
