The Most Compact Bright Radio-loud AGN -- II. VLBA Observations of Ten Sources at 43 and 86~GHz
X. -P. Cheng, T. An, X. -Y. Hong +10
Radio-loud active galactic nuclei (AGNs), hosting powerful relativistic jet outflows, provide an excellent laboratory for studying jet physics. Very long baseline interferometry (V…
The radio structure of the peculiar narrow-line Seyfert 1 galaxy candidate J1100+4421
K. É. Gabányi, S. Frey, Z. Paragi +5
Narrow-line Seyfert 1 galaxies (NLS1) are an intriguing subclass of active galactic nuclei. Their observed properties indicate low central black hole mass and high accretion rate.…
VLBI observations of four radio quasars at : blazars or not?
H. -M. Cao, S. Frey, K. É. Gabányi +5
Blazars are active galactic nuclei (AGN) whose relativistic jets point nearly to the line of sight. Their compact radio structure can be imaged with very long baseline interferomet…
Searching for a pair of accreting supermassive black holes in J1425+3231
K. É. Gabányi, S. Frey, Z. Paragi +2
In hierarchical structure formation scenarios, merging galaxies are expected to be seen in different phases of their coalescence. Simulations suggest that simultaneous activity of…
