The first Murchison Widefield Array low frequency radio observations of cluster scale non-thermal emission : the case of Abell 3667
(2014-11-21)
We present the first Murchison Widefield Array observations of the well-known cluster of galaxies Abell 3667 (A3667) between 105 and 241 MHz. A3667 is one of the best known examples of a galaxy cluster hosting a double ...
The Murchison Widefield Array Commissioning Survey : A Low-Frequency Catalogue of 14,110 Compact Radio Sources over 6,100 Square Degrees
(2014-11-14)
We present the results of an approximately 6,100 square degree 104--196MHz radio sky survey performed with the Murchison Widefield Array during instrument commissioning between 2012 September and 2012 December: the Murchison ...
WSClean : an implementation of a fast, generic wide-field imager for radio astronomy
(2014-10-11)
Astronomical widefield imaging of interferometric radio data is computationally expensive, especially for the large data volumes created by modern non-coplanar many-element arrays. We present a new widefield interferometric ...
