Low Radio Frequency Observations and Spectral Modelling of the Remnant of Supernova 1987A
(2016-10-11)
We present Murchison Widefield Array observations of the supernova remnant (SNR) 1987A between 72 and 230 MHz, representing the lowest frequency observations of the source to date. This large lever arm in frequency space ...
Low frequency observations of linearly polarized structures in the interstellar medium near the south Galactic pole
(2016-10-10)
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 deep observations allows an in-band, ...
A Large Scale, Low Frequency Murchison Widefield Array Survey of Galactic HII regions between 260\340
(2016-05-17)
We have compiled a catalogue of HII regions detected with the Murchison Widefield Array (MWA) between 72 and 231MHz. The multiple frequency bands provided by the MWA allow us identify the characteristic spectrum generated ...
High-energy sources at low radio frequency : the Murchison Widefield Array view of Fermi blazars
(2016-04-01)
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 sources, blazars are so far poorly studied at ...
