Science Pipelines for the Square Kilometre Array
Jamie Farnes, Ben Mort, Fred Dulwich +2
The Square Kilometre Array (SKA) will be both the largest radio telescope ever constructed and the largest Big Data project in the known Universe. The first phase of the project wi…
Baseline Dependent Averaging in Radio Interferometry
S. J. Wijnholds, A. G. Willis, S. Salvini
This paper presents a detailed analysis of the applicability and benefits of baseline dependent averaging (BDA) in modern radio interferometers and in particular the Square Kilomet…
Limits on Fast Radio Bursts at 145 MHz with ARTEMIS, a real-time software backend
A. Karastergiou, J. Chennamangalam, W. Armour +22
Fast Radio Bursts (FRBs), are millisecond radio signals that exhibit dispersion larger than what the Galactic electron density can account for. We have conducted a 1446 hour survey…
Fast gain calibration in radio astronomy using alternating direction implicit methods: Analysis and applications
Stefano Salvini, Stefan J. Wijnholds
Context. Modern radio astronomical arrays have (or will have) more than one order of magnitude more receivers than classical synthesis arrays, such as the VLA and the WSRT. This ma…
A GPU-based survey for millisecond radio transients using ARTEMIS
W. Armour, A. Karastergiou, M. Giles +7
Astrophysical radio transients are excellent probes of extreme physical processes originating from compact sources within our Galaxy and beyond. Radio frequency signals emitted fro…
Real-time, fast radio transient searches with GPU de-dispersion
Alessio Magro, Aris Karastergiou, Stefano Salvini +3
The identification, and subsequent discovery, of fast radio transients through blind-search surveys requires a large amount of processing power, in worst cases scaling as $\mathcal…
