DiFX2: A more flexible, efficient, robust and powerful software correlator
A. T. Deller, W. F. Brisken, C. J. Phillips +8
Software correlation, where a correlation algorithm written in a high-level language such as C++ is run on commodity computer hardware, has become increasingly attractive for small…
Follow up of GW170817 and its electromagnetic counterpart by Australian-led observing programs
I. Andreoni, K. Ackley, J. Cooke +122
The discovery of the first electromagnetic counterpart to a gravitational wave signal has generated follow-up observations by over 50 facilities world-wide, ushering in the new era…
GaLactic and Extragalactic All-sky Murchison Widefield Array (GLEAM) survey III: South Galactic Pole data release
T. Franzen, N. Hurley-Walker, S. White +5
We present the South Galactic Pole (SGP) data release from the GaLactic and Extragalactic All-sky Murchison Widefield Array (GLEAM) survey. These data combine both years of GLEAM o…
GPUs for data processing in the MWA
S. Ord, L. Greenhill, R. Wayth +4
The MWA is a next-generation radio interferometer under construction in remote Western Australia. The data rate from the correlator makes storing the raw data infeasible, so the da…
Spectroscopy with the Engineering Development Array: cold H at 63 MHz towards the Galactic Centre
J. B. R. Oonk, E. L. Alexander, J. W. Broderick +2
The Engineering Development Array (EDA) is a single test station for Square Kilometre Array (SKA) precursor technology. We have used the EDA to detect low-frequency radio recombina…
A Fast Radio Burst Host Galaxy
E. F. Keane, S. Johnston, S. Bhandari +38
In recent years, millisecond duration radio signals originating from distant galaxies appear to have been discovered in the so-called Fast Radio Bursts. These signals are dispersed…
The Aperture Array Verification System 1: System overview and early commissioning results
P. Benthem, R. Wayth, E. de Lera Acedo +51
The design and development process for the Square Kilometre Array (SKA) radio telescope, the Low Frequency Aperture Array component, was progressed during the SKA pre-construction…
A search for long-timescale, low-frequency radio transients
Tara Murphy, David L. Kaplan, Steve Croft +30
We present a search for transient and highly variable sources at low radio frequencies (150-200 MHz) that explores long timescales of 1-3 years. We conducted this search by compari…
Differential Microlensing Measurements of Quasar Broad Line Kinematics in Q2237+0305
M. O'Dowd, N. F. Bate, R. L. Webster +2
The detailed workings of the central engines of powerful quasars remain a mystery. This is primarily due to the fact that, at their cosmological distances, the inner regions of the…
The Commensal Real-time ASKAP Fast Transients (CRAFT) survey
Jean-Pierre Macquart, the CRAFT collaboration, : +37
We are developing a purely commensal survey experiment for fast (<5s) transient radio sources. Short-timescale transients are associated with the most energetic and brightest singl…
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…
