There is an observed discrepancy of nearly 700 sources between theory and observation for the supernova remnants (SNRs) population in the Galactic plane. Their mean radio spectral index of −0.5 makes these objects brighter at low frequencies.
The Murchison Widefield Array, a low-frequency radio interferometer, is a useful resource in detecting radio emissions from SNRs thanks to the wide...
The Murchison Widefield Array (MWA) has over the last ten years has conducted multiple surveys - one of the most notable being the Galactic and Extragalactic All-sky MWA survey (GLEAM). GLEAM was observed at five frequencies initially, covering 72 to 231 MHz, but was also followed up by similar observations at 300 MHz. While 300 MHz MWA data have been a much more difficult calibration and...
