A Near-Field Treatment of Aperture Synthesis Techniques using the Murchison Widefield Array
Steve Prabu, Steven J. Tingay, Andrew Williams
Typical radio interferometer observations are performed assuming the source of radiation to be in the far-field of the instrument, resulting in a two-dimensional Fourier relationsh…
MWA rapid follow-up of gravitational wave transients: prospects for detecting prompt radio counterparts
J. Tian, G. E. Anderson, A. J. Cooper +17
We present and evaluate the prospects for detecting coherent radio counterparts to gravitational wave (GW) events using Murchison Widefield Array (MWA) triggered observations. The…
Detection of intended and unintended emissions from Starlink satellites in the SKA-Low frequency range, at the SKA-Low site, with an SKA-Low station analog
Dylan Grigg, Steven Tingay, Marcin Sokolowski +3
Intended and unintended radio emissions from satellites can interfere with sensitive radio telescopes in the frequency ranges of key experiments in astrophysics and cosmology. We d…
Searches for neutrinos in the direction of radio-bright blazars with the ANTARES telescope
ANTARES Collaboration, A. Albert, S. Alves +162
Active galaxies, especially blazars, are among the most promising neutrino source candidates. To date, ANTARES searches for these objects considered GeV-TeV -ray bright blazars.…
Probing the jet size of two Black hole X-ray Binaries in the hard state
S. Prabu, J. C. A. Miller-Jones, A. Bahramian +5
Using multi-frequency Very Long Baseline Interferometer (VLBI) observations, we probe the jet size in the optically thick hard state jets of two black hole X-ray binary (BHXRB) sys…
Demonstration of Orbit Determination for LEO Objects using the Murchison Widefield Array
S. Prabu, P. Hancock, X. Xiang +1
The rapidly increasing number of satellites in Earth's orbit motivates the development of Space Domain Awareness (SDA) capabilities using wide field-of-view sensor systems that can…
