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…

Searching for axion dark matter with MeerKAT Radio Telescope

Yun-Fan Zhou, Nick Houston, Gyula I. G. Jozsa +11

Axions provide a natural and well-motivated dark matter candidate, with the capability to convert directly to photons in the presence of an electromagnetic field. A particularly co…

VLBI observations of VIK J2318-3113, a quasar at z = 6.44

Y. Zhang, T. An, A. Wang +5

The nature of jets in active galactic nuclei (AGN) in the early Universe and their feedback to the host galaxy remain a highly topical question. Observations of the radio structure…

The radio structure of 3C 316, a galaxy with double-peaked narrow optical emission lines

T. An, Z. Paragi, S. Frey +6

The galaxy 3C\,316 is the brightest in the radio band among the optically-selected candidates exhibiting double-peaked narrow optical emission lines. Observations with the Very Lar…

A compact radio source in the high-redshift soft gamma-ray blazar IGR J12319-0749

S. Frey, Z. Paragi, K. E. Gabanyi +1

Context. Blazars are powerful active galactic nuclei (AGNs) radiating prominently in the whole electromagnetic spectrum, from the radio to the X-ray and gamma-ray bands. Their emis…

Two in one? A possible dual radio-emitting nucleus in the quasar SDSS J1425+3231

S. Frey, Z. Paragi, T. An +1

The radio-emitting quasar SDSS J1425+3231 (z=0.478) was recently found to have double-peaked narrow [O III] optical emission lines. Based on the analysis of the optical spectrum, P…
