First Limits on the 21 cm Power Spectrum during the Epoch of X-ray heating
A. Ewall-Wice, Joshua S. Dillon, J. N. Hewitt +62
We present first results from radio observations with the Murchison Widefield Array seeking to constrain the power spectrum of 21 cm brightness temperature fluctuations between the…
The giant lobes of Centaurus A observed at 118 MHz with the Murchison Widefield Array
B. McKinley, F. Briggs, B. M. Gaensler +50
We present new wide-field observations of Centaurus A (Cen A) and the surrounding region at 118 MHz with the Murchison Widefield Array (MWA) 32-tile prototype, with which we invest…
A 189 MHz, 2400 square degree polarization survey with the Murchison Widefield Array 32-element prototype
G. Bernardi, L. J. Greenhill, D. A. Mitchell +50
We present a Stokes I, Q and U survey at 189 MHz with the Murchison Widefield Array 32-element prototype covering 2400 square degrees. The survey has a 15.6 arcmin angular resoluti…
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…
