The Aperture Array Verification System 1: System overview and early commissioning results
P. Benthem, R. Wayth, E. de Lera Acedo +51
The design and development process for the Square Kilometre Array (SKA) radio telescope, the Low Frequency Aperture Array component, was progressed during the SKA pre-construction…
Testing the violation of the equivalence principle in the electromagnetic sector and its consequences in gravity
Jackson Levi Said, Jurgen Mifsud, David Parkinson +3
A violation of the distance-duality relation is directly linked with a temporal variation of the electromagnetic fine-structure constant. We consider a number of well-studied $f(T)…
On-sky calibration of a SKA1-low station in the presence of mutual coupling
Josef Borg, Alessio Magro, Kristian Zarb Adami +3
This paper deals with the calibration of the analogue chains of a Square Kilometre Array (SKA) phased aperture array station, using embedded element patterns (one per antenna in th…
Signal Processing Firmware for the Low Frequency Aperture Array
Gianni Comoretto, Riccardo Chiello, Matt Roberts +22
The signal processing firmware that has been developed for the Low Frequency Aperture Array component of the Square Kilometre Array is described. The firmware is implemented on a d…
GPU-Powered Coherent Beamforming
Alessio Magro, Kristian Zarb Adami, Jack Hickish
GPU-based beamforming is a relatively unexplored area in radio astronomy, possibly due to the assumption that any such system will be severely limited by the PCIe bandwidth require…
GREAT3 results I: systematic errors in shear estimation and the impact of real galaxy morphology
Rachel Mandelbaum, Barnaby Rowe, Robert Armstrong +40
We present first results from the third GRavitational lEnsing Accuracy Testing (GREAT3) challenge, the third in a sequence of challenges for testing methods of inferring weak gravi…
