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 É. 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…

SDSSJ110546.07+145202.4: The first long-duration radio changing-look NLS1 galaxy

S. Komossa, D. Grupe, A. Kraus +12

SDSSJ110546.07+145202.4 stands out as a unique radio changing-look Narrow-line Seyfert 1 (NLS1) galaxy that has brightened dramatically and shows an exceptionally long duration of…

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…
