Cleaning radio interferometric images using a spherical wavelet decomposition
Chris J. Skipper, Anna M. M. Scaife, Jason D. McEwen
The deconvolution, or cleaning, of radio interferometric images often involves computing model visibilities from a list of clean components, in order that the contribution from the…
Fast W-Projection for Wide-field Imaging
Luis F. R. Lucas, Chris J. Skipper, Anna M. M. Scaife
Wide-field imaging has become a major challenge for modern radio astronomy, which uses high sensitivity acquisition systems that deal with huge amounts of data. In this paper we in…
Transfer learning for radio galaxy classification
Hongming Tang, Anna M. M. Scaife, J. P. Leahy
In the context of radio galaxy classification, most state-of-the-art neural network algorithms have been focused on single survey data. The question of whether these trained algori…
Efficient Source Finding for Radio Interferometric Images
Luis Lucas, Tim Staley, Anna Scaife
Object detection in astronomical images, generically referred to as source finding, is often performed before the object characterisation stage in astrophysical processing work flo…
