High-resolution radio observations of TeV candidate sources
J. Kőmíves, K. É. 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…
European VLBI Network observations of the peculiar radio source 4C 35.06 overlapping with a compact group of nine galaxies
Patrik Milán Veres, Krisztina Éva Gabányi, Sándor Frey +8
Context. According to the hierarchical structure formation model, brightest cluster galaxies (BCGs) evolve into the most luminous and massive galaxies in the Universe through multi…
From binary to singular: the AGN PSO J334.2028+1.4075 under the high-resolution scope
P. Benke, K. É. Gabányi, S. Frey +6
PSO J334.2028+1.4075 (PSO J334) is a luminous quasar located at redshift z=2.06. The source gained attention when periodic flux density variations were discovered in its optical li…
Searching for the Origin of Double-peaked Broad Emission Lines in a Merging Galaxy with EVN
Krisztina É. Gabányi, Sándor Frey, Emma Kun +2
The current cosmological structure formation models predict that galaxies evolve through frequent mergers. During these events, the supermassive black holes (SMBHs) residing in the…
The rise and fall of a binary AGN candidate: the story of PSO J334.2028+1.4075
P. Benke, S. Frey, K. É. Gabányi +7
Apparently periodic optical variations of the luminous high-redshift (z=2.06) quasar PSO J334.2028+1.4075 led Liu et al. (2015) to interpret the variability as the orbital period o…
Disclosing the properties of low-redshift dual AGN through XMM-Newton and SDSS spectroscopy
A. De Rosa, C. Vignali, B. Husemann +10
We report on an optical (SDSS) and X-ray (XMM) study of an optically selected sample of four dual AGN systems at projected separations of 30--60~kpc. All sources are detected in th…
