Fast jet proper motion discovered in a blazar at z = 4.72
Yingkang Zhang, Tao An, Sandor Frey
High-resolution observations of high-redshift () radio quasars offer a unique insight into jet kinematics at early cosmological epochs, as well as constraints on cosmological…
Unveiling the weak radio quasar population at z 4
Krisztina Perger, Sándor Frey, Krisztina É. Gabányi +1
We applied image stacking on empty-field Faint Images of the Radio Sky at Twenty-Centimeters (FIRST) survey maps centred on optically identified high-redshift quasars at t…
Very long baseline interferometry observation of the triple AGN candidate J0849+1114
Krisztina Éva Gabányi, Sándor Frey, Shobita Satyapal +2
In the hierarchical structure formation model, galaxies grow through various merging events. Numerical simulations indicate that the mergers can enhance the activity of the central…
Detection statistics of the RadioAstron AGN survey
Y. Y. Kovalev, N. S. Kardashev, K. V. Sokolovsky +57
The largest Key Science Program of the RadioAstron space VLBI mission is a survey of active galactic nuclei (AGN). The main goal of the survey is to measure and study the brightnes…
TeraHertz Exploration and Zooming-in for Astrophysics (THEZA): ESA Voyage 2050 White Paper
Leonid I. Gurvits, Zsolt Paragi, Viviana Casasola +32
This paper presents the ESA Voyage 2050 White Paper for a concept of TeraHertz Exploration and Zooming-in for Astrophysics (THEZA). It addresses the science case and some implement…
The rare extended radio-loud narrow-line Seyfert 1 galaxy SDSS J1030+5516 at high resolution
Krisztina Éva Gabányi, Sándor Frey, Péter Veres +1
Recently, Rakshit et al. (2018) reported the discovery of SDSS J103024.95551622.7, a radio-loud narrow-line Seyfert 1 galaxy having a kpc scale double-lobed radio str…
