Very Long Baseline Interferometry with the SKA Observatory
J. F. Radcliffe, J. Yang, Z. Paragi +129
Very Long Baseline Interferometry (VLBI) is a fundamental technique that combines signals from telescopes separated by thousands of kilometres to obtain some of the highest-resolut…
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…
Continuum source catalog for the first APERTIF data release
A. M. Kutkin, T. A. Oosterloo, R. Morganti +25
The first data release of Apertif survey contains 3074 radio continuum images covering a thousand square degrees of the sky. The observations were performed during August 2019 to J…
First release of Apertif imaging survey data
Elizabeth A. K. Adams, B. Adebahr, W. J. G. de Blok +56
(Abridged) Apertif is a phased-array feed system for WSRT, providing forty instantaneous beams over 300 MHz of bandwidth. A dedicated survey program started on 1 July 2019, with th…
Characterising the Apertif primary beam response
H. Dénes, K. M. Hess, E. A. K. Adams +27
Context. Phased Array Feeds (PAFs) are multi element receivers in the focal plane of a telescope that make it possible to form simultaneously multiple beams on the sky by combining…
Apercal -- The Apertif Calibration Pipeline
B. Adebahr, R. Schulz, T. J. Dijkema +33
Apertif (APERture Tile In Focus) is one of the Square Kilometre Array (SKA) pathfinder facilities. The Apertif project is an upgrade to the 50-year-old Westerbork Synthesis Radio T…
