Calibration and Stokes Imaging with Full Embedded Element Primary Beam Model for the Murchison Widefield Array
M. Sokolowski, T. Colegate, A. T. Sutinjo +22
The Murchison Widefield Array (MWA), located in Western Australia, is one of the low-frequency precursors of the international Square Kilometre Array (SKA) project. In addition to…
The Spectral Energy Distribution of Powerful Starburst Galaxies I: Modelling the Radio Continuum
T J Galvin, N Seymour, J Marvil +24
We have acquired radio continuum data between 70\,MHz and 48\,GHz for a sample of 19 southern starburst galaxies at moderate redshifts () with the aim of separat…
A high resolution foreground model for the MWA EoR1 field: model and implications for EoR power spectrum analysis
P. Procopio, R. B. Wayth, J. Line +23
The current generation of experiments aiming to detect the neutral hydrogen signal from the Epoch of Reionisation (EoR) is likely to be limited by systematic effects associated wit…
Diffuse galaxy cluster emission at 168 MHz within the Murchison Widefield Array Epoch of Reionization 0-hour field
S. W. Duchesne, M. Johnston-Hollitt, A. R. Offringa +3
We detect and characterise extended, diffuse radio emission from galaxy clusters at 168 MHz within the Epoch of Reionization 0-hour field: a region of th…
Low frequency spectral energy distributions of radio pulsars detected with the Murchison Widefield Array
Tara Murphy, David L. Kaplan, Martin E. Bell +24
We present low-frequency spectral energy distributions of 60 known radio pulsars observed with the Murchison Widefield Array (MWA) telescope. We searched the GaLactic and Extragala…
Spectral energy distribution and radio halo of NGC 253 at low radio frequencies
A. D. Kapinska, L. Staveley-Smith, R. Crocker +67
We present new radio continuum observations of NGC253 from the Murchison Widefield Array at frequencies between 76 and 227 MHz. We model the broadband radio spectral energy distrib…
