Dark matter annihilation in Centauri: Astrophysical implications derived from the MWA radio data
Arpan Kar, Biswarup Mukhopadhyaya, Steven Tingay +6
We present an analysis of Murchison Widefield Array radio telescope data from Cen, possibly a stripped dwarf spheroidal galaxy core captured by our Galaxy. Recent interpretatio…
New candidate radio supernova remnants detected in the GLEAM survey over ,
Natasha Hurley-Walker, Miroslav D. Filipovic, Bryan M. Gaensler +18
We have detected 27 new supernova remnants (SNRs) using a new data release of the GLEAM survey from the Murchison Widefield Array (MWA) telescope, including the lowest surface-brig…
Candidate radio supernova remnants observed by the GLEAM survey over and
Natasha Hurley-Walker, Bryan M. Gaensler, Denis A. Leahy +18
We examined the latest data release from the GaLactic and Extragalactic All-sky Murchison Widefield Array (GLEAM) survey covering , $180^\circ < l < 240^\…
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…
Low Radio Frequency Observations and Spectral Modelling of the Remnant of Supernova 1987A
J. R. Callingham, B. M. Gaensler, G. Zanardo +17
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.…
Giant lobes of Centaurus A as seen in radio and gamma-ray images obtained with the Fermi-LAT and Planck satellites
Xiao-na Sun, Rui-zhi Yang, Benjamin Mckinley +1
The γ-ray data of Fermi-LAT on the giant lobes of Centaurus A are analysed together with the high frequency radio data obtained with the Planck satellite. The large γ-ray photon st…
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…
Modelling of the Spectral Energy Distribution of Fornax A: Leptonic and Hadronic Production of High Energy Emission from the Radio Lobes
B. McKinley, R. Yang, M. López-Caniego +52
We present new low-frequency observations of the nearby radio galaxy Fornax A at 154 MHz with the Murchison Widefield Array, microwave flux-density measurements obtained from WMAP…
