The Total and Polarized Radio Emission from the Innermost Jets of a High-Redshift Quasar and a Candidate at Parsec-Scale Resolution
Bence Husvéth, Krisztina É. Gabányi, Tao An +4
High-frequency very long baseline interferometry (VLBI) polarimetry probes synchrotron-emitting plasma closer to the central engines of radio-loud active galactic nuclei (AGNs), bu…
Radio Properties of Narrow-Line and Broad-Line Seyfert 1 Galaxies
K. É. Gabányi, S. Komossa, A. Mezősi +2
Narrow-line Seyfert 1 (NLS1) galaxies host active galactic nuclei (AGN) with narrow optical emission lines of the broad-line region. This is often explained with a relatively lower…
Radio Jet Properties of the Flaring Gamma-Ray Blazar PKS 0346-27
Máté Krezinger, Sándor Frey, Krisztina Ã. Gabányi
The blazar PKS 0346-27 at redshift z=0.991 is among the most distant extragalactic sources detected in very high energy gamma-rays. It underwent a major flare reaching TeV energies…
Direct VLBI evidence for a buried AGN in the triple-merger LIRG UGC 2369S
Wancheng Xu, Sándor Frey, Lang Cui +1
UGC 2369S is a luminous infrared galaxy (LIRG) undergoing a late-stage merger in a triple system, where the heavily obscured northern core is suspected to host an active galactic n…
Milliarcsecond-resolution Radio-imaging Survey of Blazar Candidates at 4 < z < 5.4
Máté Krezinger, Alessandro Caccianiga, Daniele Dallacasa +9
We present a milliarcsecond-resolution radio survey of 17 high-redshift (4 < z < 5.4) blazar candidates observed with the European Very Long Baseline Interferometry (VLBI) Network…
An Ejection Event Captured by VLBI During the Outburst of Swift J1727.81613
Hongmin Cao, Jun Yang, Sándor Frey +9
We observed a newly-discovered Galactic black hole X-ray binary Swift J1727.81613 with the European Very Long Baseline Interferometry Network (EVN) at 5 GHz. The observation was…
