Realisation of a low frequency SKA Precursor: The Murchison Widefield Array
S. J. Tingay, R. Goeke, J. N. Hewitt +56
The Murchison Widefield Array is a low frequency (80 - 300 MHz) SKA Precursor, comprising 128 aperture array elements distributed over an area of 3 km diameter. The MWA is located…
Science with the Murchison Widefield Array
Judd D. Bowman, Iver Cairns, David L. Kaplan +58
Significant new opportunities for astrophysics and cosmology have been identified at low radio frequencies. The Murchison Widefield Array is the first telescope in the Southern Hem…
Fast Holographic Deconvolution: a new technique for precision radio interferometry
Ian Sullivan, Miguel Morales, Bryna Hazelton +48
We introduce the Fast Holographic Deconvolution method for analyzing interferometric radio data. Our new method is an extension of A-projection/software-holography/forward modeling…
The Murchison Widefield Array: the Square Kilometre Array Precursor at low radio frequencies
S. J. Tingay, R. Goeke, J. D. Bowman +57
The Murchison Widefield Array (MWA) is one of three Square Kilometre Array Precursor telescopes and is located at the Murchison Radio-astronomy Observatory in the Murchison Shire o…
First Light for the First Station of the Long Wavelength Array
G. B. Taylor, S. W. Ellingson, N. E. Kassim +32
The first station of the Long Wavelength Array (LWA1) was completed in April 2011 and is currently performing observations resulting from its first call for proposals in addition t…
Direction-Dependent Polarised Primary Beams in Wide-Field Synthesis Imaging
Daniel A. Mitchell, Randall B. Wayth, Gianni Bernardi +2
The process of wide-field synthesis imaging is explored, with the aim of understanding the implications of variable, polarised primary beams for forthcoming Epoch of Reionisation e…
