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…
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…
Sub-mJy radio emission from high-redshift active galactic nuclei in the footprint of the VLA Sky Survey
Krisztina Perger, Sándor Frey, Krisztina É. Gabányi
Using empty-field `Quick Look' images from the first two epochs of the VLA Sky Survey (VLASS) observations, centred on the positions of individually radio-non-detected a…
Radio and mid-infrared properties of the blazar J14190838
Krisztina Perger, Sándor Frey, Krisztina Éva Gabányi
The radio quasar NVSS J141922083830 (J14190838) was initially classified as an uncategorised blazar-type object, following its detection in the -ray band with the Fermi sp…
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…
Very long baseline interferometry observations of the high-redshift blazar candidate J0141-5427
K. É. Gabányi, S. Belladitta, S. Frey +7
Active galactic nuclei (AGN) have been observed as far as redshift z~7. They are crucial in investigating the early Universe as well as the growth of supermassive black holes at th…
