We are developing a purely commensal survey experiment for fast (<5 s) transient radio sources. Short-timescale transients are associated with the most energetic and brightest single events in the Universe. Our objective is to cover the enormous volume of transients parameter space made available by ASKAP, with an unprecedented combination of sensitivity(More)
The future of cm and m-wave astronomy lies with the Square Kilometre Array (SKA), a telescope under development by a consortium of 17 countries that will be 50 times more sensitive than any existing radio facility. A majority of the key science for the SKA will be addressed through large-area imaging of the Universe at frequencies from a few hundred MHz to(More)
Pulsars are rotating neutron stars, sweeping the emission regions from the magnetic poles across our line of sight. Isolated neutron stars lose angular momentum through dipole radiation and (possibly) particle winds, hence they slow down extremely steadily, making them amongst the most reliable timing sources available. However, it is well known that(More)
The Vela pulsar is the brightest pulsar at radio wavelengths. It was the object that told us (via its glitching) that pulsars were solid rotating bodies not oscillating ones. Along with the Crab pulsar is it the source of many of the models of pulsar behaviour. Therefore it is of vital importance to know how far away it is, and its origin. The proper motion(More)
We report on Chandra ACIS imaging of the pulsar wind nebula (PWN) of the young Vela-like PSR B1706−44, which shows the now common pattern of an equatorial wind and polar jets. The structure is particularly rich, showing a relativistically boosted termination shock, jets with strong confinement, a surrounding radio/X-ray PWN and evidence for a quasi-static(More)
Radio Astronomy demands for HPC power have been rising and are expected to reach exaflop scale by 2020. To address such huge demands for compute, users are testing newer CPU architectures and accelerator architectures such as GPUs and FPGAs. Intel, with the help of HPC Ecosystem partners, has stated a goal to deliver exascale computing capability by 2018.(More)
Relative astrometry of the J=1→0, v=1 and v=2 SiO masers towards R Leonis Minoris using VERA Abstract Oxygen-rich Asymptotic Giant Branch (AGB) stars are intense emitters of SiO and H 2 O maser lines at 43 (J=1→0, v=1 and 2) and 22 GHz, respectively. VLBI observations of the maser emission provides a unique tool to sample the innermost layers of the(More)
