Efficient wide-field radio interferometry response
Philipp Arras, Martin Reinecke, Rüdiger Westermann +1
Radio interferometers do not measure the sky brightness distribution directly but rather a modified Fourier transform of it. Imaging algorithms, thus, need a computational represen…
Comparison of classical and Bayesian imaging in radio interferometry
Philipp Arras, Hertzog L. Bester, Richard A. Perley +4
CLEAN, the commonly employed imaging algorithm in radio interferometry, suffers from a number of shortcomings: in its basic version it does not have the concept of diffuse flux, an…
Unified Radio Interferometric Calibration and Imaging with Joint Uncertainty Quantification
Philipp Arras, Philipp Frank, Reimar Leike +2
The data reduction procedure for radio interferometers can be viewed as a combined calibration and imaging problem. We present an algorithm that unifies cross-calibration, self-cal…
