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…
High-energy sources at low radio frequency: the Murchison Widefield Array view of Fermi blazars
M. Giroletti, F. Massaro, R. D'Abrusco +54
Low-frequency radio arrays are opening a new window for the study of the sky, both to study new phenomena and to better characterize known source classes. Being flat-spectrum sourc…
Beamforming Errors in Murchison Widefield Array Phased Array Antennas and their effects on Epoch of Reionization Science
A. R. Neben, J. N. Hewitt, R. F. Bradley +28
Accurate antenna beam models are critical for radio observations aiming to isolate the redshifted 21cm spectral line emission from the Dark Ages and the Epoch of Reionization and u…
An analysis of the halo and relic radio emission from Abell 3376 from Murchison Widefield Array observations
Lijo T. George, K. S. Dwarakanath, M. Johnston-Hollitt +48
We have carried out multiwavelength observations of the near-by () rich, merging galaxy cluster Abell 3376 with the Murchison Widefield Array (MWA). As a part of the GaLac…
A Digital-Receiver for the Murchison Widefield Array
Thiagaraj Prabu, K. S. Srivani, D. Anish Roshi +55
An FPGA-based digital-receiver has been developed for a low-frequency imaging radio interferometer, the Murchison Widefield Array (MWA). The MWA, located at the Murchison Radio-ast…
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…
