Very Long Baseline Array Observations of Parsec-scale Radio Emission in Dual Active Galactic Nuclei
Wancheng Xu, Lang Cui, Xiang Liu +11
It is believed that dual active galactic nuclei (dual AGN) will form during galaxies merge. Studying dual-AGN emission can provide valuable insights into galaxy merging and evoluti…
A small radio galaxy at z=4.026
Krisztina É. Gabányi, Sándor Frey, Tao An +8
Less than radio-loud active galactic nuclei (AGN) are known above redshift . Around of them have been observed at milliarcsecond (mas) scale resolution with very long…
Three little radio galaxies in the early Universe
K. É. Gabányi, S. Frey, Z. Paragi +7
Volonteri et al. (2011) found that the number of radio-loud quasars above redshift 4 calculated from the luminosity function (based upon Swift/BAT observations) is much smaller tha…
The loud and the quiet: searching for radio counterparts of two radio-weak BL Lac candidates with VLBI
Hong-Min Cao, Sándor Frey, Krisztina É. Gabányi +4
BL Lac objects are known to have compact jets inclined to our line of sight at a small angle, showing prominent radio emission. Two radio-weak BL Lac candidates with no counterpart…
Constraining the radio jet proper motion of the high-redshift quasar J2134-0419 at z=4.3
K. Perger, S. Frey, K. É. Gabányi +12
To date, PMN J2134-0419 (at a redshift z=4.33) is the second most distant quasar known with a milliarcsecond-scale morphology permitting direct estimates of the jet proper motion.…
