Wide-band Rotation Measure Synthesis
Luke Pratley, Melanie Johnston-Hollitt
Rotation measure synthesis allows the estimation of Faraday dispersion via a Fourier transform and is the primary tool to probe cosmic magnetic fields. We show this can be consider…
Load balancing for distributed interferometric image reconstruction
Luke Pratley, Jason D. McEwen
We present a new algorithm to perform wide-field radio interferometric image reconstruction, with exact non-coplanar correction, that scales to big-data. This algorithm allows us t…
-stacking -projection hybrid algorithm for wide-field interferometric imaging: implementation details and improvements
L. Pratley, M. Johnston-Hollitt, J. D. McEwen
We present a detailed discussion of the implementation strategies for a recently developed -stacking -projection hybrid algorithm used to reconstruct wide-field interferometr…
Sparse Image Reconstruction for the SPIDER Optical Interferometric Telescope
Luke Pratley, Jason D. McEwen
The concept of a recently proposed small-scale interferometric optical imaging device, an instrument known as the Segmented Planar Imaging Detector for Electro-optical Reconnaissan…
Distributed and parallel sparse convex optimization for radio interferometry with PURIFY
Luke Pratley, Jason D. McEwen, Mayeul d'Avezac +4
Next generation radio interferometric telescopes are entering an era of big data with extremely large data sets. While these telescopes can observe the sky in higher sensitivity an…
