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…
Planetary Radio Interferometry and Doppler Experiment (PRIDE) of the JUICE mission
Leonid I. Gurvits, Giuseppe Cimo, Dominic Dirkx +20
Planetary Radio Interferometry and Doppler Experiment (PRIDE) is a multi-purpose experimental technique aimed at enhancing the science return of planetary missions. The technique e…
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…
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…
J2102+6015: a potential distant multimessenger?
Leonid I. Gurvits, Sándor Frey, Máté Krezinger +7
We present and briefly discuss results of several studies of the source J2102+6015 with tentatively defined redshift z=4:575 which demonstrates unusual properties in imaging and as…
