Spectral indices in active galactic nuclei as seen by Apertif and LOFAR
A. M. Kutkin, R. Morganti, T. A. Oosterloo +5
We present two new radio continuum images obtained with Apertif at 1.4 GHz. The images, produced with a direction-dependent calibration pipeline, cover 136 square degrees of the Lo…
Apertif 1.4 GHz continuum observations of the Boötes field and their combined view with LOFAR
A. M. Kutkin, T. A. Oosterloo, R. Morganti +17
We present a new image of a 26.5 square degree region in the Boötes constellation obtained at 1.4 GHz using the Aperture Tile in Focus (Apertif) system on the Westerbork Synthesis…
An interference detection strategy for Apertif based on AOFlagger 3
A. R. Offringa, B. Adebahr, A. Kutkin +15
Context. Apertif is a multi-beam receiver system for the Westerbork Synthesis Radio Telescope that operates at 1.1-1.5 GHz, which overlaps with various radio services, resulting in…
The Apertif science verification campaign - Characteristics of polarised radio sources
B. Adebahr, A. Berger, E. A. K. Adams +24
We analyse five early science datasets from the APERture Tile in Focus (Apertif) phased array feed system to verify the polarisation capabilities of Apertif in view of future large…
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…
A search for radio emission from double-neutron star merger GW190425 using Apertif
Olivér Boersma, Joeri van Leeuwen, Elizabeth A. K. Adams +26
Detection of the electromagnetic emission from coalescing binary neutron stars (BNS) is important for understanding the merger and afterglow. We present a search for a radio counte…
Chromatic periodic activity down to 120 MHz in a Fast Radio Burst
Inés Pastor-Marazuela, Liam Connor, Joeri van Leeuwen +34
Fast radio bursts (FRBs) are extragalactic astrophysical transients whose brightness requires emitters that are highly energetic, yet compact enough to produce the short, milliseco…
