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…
Removal and replacement of interference in tied-array radio pulsar observations using the spectral kurtosis estimator
M. Purver, C. G. Bassa, I. Cognard +10
We describe how to implement the spectral kurtosis method of interference removal (zapping) on a digitized signal of averaged power values. Spectral kurtosis is a hypothesis test,…
The beamformer and correlator for the Large European Array for Pulsars
R. Smits, C. G. Bassa, G. H. Janssen +10
The Large European Array for Pulsars combines Europe's largest radio telescopes to form a tied-array telescope that provides high signal-to-noise observations of millisecond pulsar…
Pulsar observations with European telescopes for testing gravity and detecting gravitational waves
D. Perrodin, C. G. Bassa, G. H. Janssen +20
A background of nanohertz gravitational waves from supermassive black hole binaries could soon be detected by pulsar timing arrays, which measure the times-of-arrival of radio puls…
From Spin Noise to Systematics: Stochastic Processes in the First International Pulsar Timing Array Data Release
L. Lentati, R. M. Shannon, W. A. Coles +80
We analyse the stochastic properties of the 49 pulsars that comprise the first International Pulsar Timing Array (IPTA) data release. We use Bayesian methodology, performing model…
