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…
A Matched Filter Technique For Slow Radio Transient Detection And First Demonstration With The Murchison Widefield Array
L. Feng, R. Vaulin, J. N. Hewitt +30
Many astronomical sources produce transient phenomena at radio frequencies, but the transient sky at low frequencies (<300 MHz) remains relatively unexplored. Blind surveys with ne…
The Hydrogen Epoch of Reionization Array Dish III: Measuring Chromaticity of Prototype Element with Reflectometry
Nipanjana Patra, Aaron R. Parsons, David R. DeBoer +54
The experimental efforts to detect the redshifted 21 cm signal from the Epoch of Reionization (EoR) are limited predominantly by the chromatic instrumental systematic effect. The d…
