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…
Low Frequency Observations of the Moon with the Murchison Widefield Array
B. McKinley, F. Briggs, D. L. Kaplan +49
A new generation of low frequency radio telescopes is seeking to observe the redshifted 21 cm signal from the Epoch of Reionization (EoR), requiring innovative methods of calibrati…
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…
The EoR Sensitivity of the Murchison Widefield Array
A. P. Beardsley, B. J. Hazelton, M. F. Morales +48
Using the final 128 antenna locations of the Murchison Widefield Array (MWA), we calculate its sensitivity to the Epoch of Reionization (EoR) power spectrum of red- shifted 21 cm e…
Low Frequency Imaging of Fields at High Galactic Latitude with the Murchison Widefield Array 32-Element Prototype
Christopher L. Williams, Jacqueline N. Hewitt, Alan M. Levine +54
The Murchison Widefield Array (MWA) is a new low-frequency, wide field-of-view radio interferometer under development at the Murchison Radio-astronomy Observatory (MRO) in Western…
