Radio Galaxy Detection in the Visibility Domain
Adam Malyali, Marzia Rivi, Filipe B. Abdalla +1
We explore a new Bayesian method of detecting galaxies from radio interferometric data of the faint sky. Working in the Fourier domain, we fit a single, parameterised galaxy model…
Revisiting the spread spectrum effect in radio interferometric imaging: a sparse variant of the w-projection algorithm
L. Wolz, J. D. McEwen, F. B. Abdalla +2
Next-generation radio interferometric telescopes will exhibit non-coplanar baseline configurations and wide field-of-views, inducing a w-modulation of the sky image, which in turn…
Initial deep LOFAR observations of Epoch of Reionization windows: I. The North Celestial Pole
S. Yatawatta, A. G. de Bruyn, M. A. Brentjens +86
The aim of the LOFAR Epoch of Reionization (EoR) project is to detect the spectral fluctuations of the redshifted HI 21cm signal. This signal is weaker by several orders of magnitu…
