Discovery of a giant radio outburst of the narrow-line Seyfert 1 galaxy SDSS J110546.07+145202.4
K. Ã. Gabányi, S. Komossa, A. Kraus +2
We have identified a high-amplitude radio outburst in the course of a large-sample study of the radio properties of narrow-line Seyfert 1 (NLS1) galaxies. We have analysed previous…
Zooming into the neutrino-associated blazar candidate J1718+4239
K. Perger, S. Frey, K. Ã. Gabányi +1
The radio quasar NVSS~J171822+423948 (J1718+4239) was proposed as the counterpart of the IceCube neutrino event IC-201221A. To reveal the nature of the source, we conducted new ver…
High-resolution radio observations of TeV candidate sources
J. KÅmÃves, K. Ã. Gabányi, S. Frey +3
Radio-loud active galactic nuclei (AGN) with their jets pointed close to our line of sight constitute the majority of extragalactic -ray sources and significantly contribute to…
Deep silence: radio properties of little red dots
K. Perger, J. Fogasy, S. Frey +1
To investigate the radio properties of the recently found high-redshift population, we collected a sample of little red dots (LRDs) from the literature. By cross-matching the…
