The Apertif Radio Transient System (ARTS): Design, Commissioning, Data Release, and Detection of the first 5 Fast Radio Bursts
Joeri van Leeuwen, Eric Kooistra, Leon Oostrum +49
Fast Radio Bursts must be powered by uniquely energetic emission mechanisms. This requirement has eliminated a number of possible source types, but several remain. Identifying the…
A fast radio burst with sub-millisecond quasi-periodic structure
Inés Pastor-Marazuela, Joeri van Leeuwen, Anna Bilous +31
Fast radio bursts (FRBs) are extragalactic radio transients of extraordinary luminosity. Studying the diverse temporal and spectral behaviour recently observed in a number of FRBs…
Apertif, Phased Array Feeds for the Westerbork Synthesis Radio Telescope
W. A. van Cappellen, T. A. Oosterloo, M. A. W. Verheijen +87
We describe the APERture Tile In Focus (Apertif) system, a phased array feed (PAF) upgrade of the Westerbork Synthesis Radio Telescope which has transformed this telescope into a h…
The best of both worlds: Combining LOFAR and Apertif to derive resolved radio spectral index images
R. Morganti, T. A. Oosterloo, M. Brienza +36
Supermassive black holes at the centres of galaxies can cycle through periods of activity and quiescence. Characterising the duty cycle of active galactic nuclei is crucial for und…
The extreme blazar AO 0235+164 as seen by extensive ground and space radio observations
A. M. Kutkin, I. N. Pashchenko, M. M. Lisakov +10
Clues to the physical conditions in radio cores of blazars come from measurements of brightness temperatures as well as effects produced by intrinsic opacity. We study the properti…
A connection between -ray and parsec-scale radio flares in the blazar 3C 273
Mikhail Lisakov, Yuri Y. Kovalev, Tuomas Savolainen +2
We present a comprehensive 5-43 GHz VLBA study of the blazar 3C 273 initiated after an onset of a strong -ray flare in this source. We have analyzed the kinematics of new-born c…
