First Season MWA EoR Power Spectrum Results at Redshift 7
A. P. Beardsley, B. J. Hazelton, I. S. Sullivan +63
The Murchison Widefield Array (MWA) has collected hundreds of hours of Epoch of Reionization (EoR) data and now faces the challenge of overcoming foreground and systematic contamin…
Low frequency observations of linearly polarized structures in the interstellar medium near the south Galactic pole
Emil Lenc, B. M. Gaensler, X. H. Sun +76
We present deep polarimetric observations at 154 MHz with the Murchison Widefield Array (MWA), covering 625 deg^2 centered on RA=0 h, Dec=-27 deg. The sensitivity available in our…
A High Reliability Survey of Discrete Epoch of Reionization Foreground Sources in the MWA EoR0 Field
P. A. Carroll, J. Line, M. F. Morales +61
Detection of the Epoch of Reionization HI signal requires a precise understanding of the intervening galaxies and AGN, both for instrumental calibration and foreground removal. We…
The Murchison Widefield Array 21 cm Power Spectrum Analysis Methodology
Daniel C. Jacobs, B. J. Hazelton, C. M. Trott +61
We present the 21 cm power spectrum analysis approach of the Murchison Widefield Array Epoch of Reionization project. In this paper, we compare the outputs of multiple pipelines fo…
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…
