Radio polarization measurements from RRAT J1819-1458
A. Karastergiou, A. W Hotan, W. van Straten +2
We present the first polarization measurements of the radio emission from RRAT J18191458. Our observations, conducted in parallel to regular timing sessions, have yielded a smal…
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…
On the Detectability of the Hydrogen 3-cm Fine Structure Line from the EoR
Mark Dijkstra, Adam Lidz, Jonathan R. Pritchard +4
A soft ultraviolet radiation field, 10.2 eV < E <13.6 eV, that permeates neutral intergalactic gas during the Epoch of Reionization (EoR) excites the 2p (directly) and 2s (indirect…
Real-Time Calibration of the Murchison Widefield Array
D. A. Mitchell, L. J. Greenhill, R. B. Wayth +5
The interferometric technique known as peeling addresses many of the challenges faced when observing with low-frequency radio arrays, and is a promising tool for the associated cal…
The Magnetic Field of the Solar Corona from Pulsar Observations
S. M. Ord, S. Johnston, J. Sarkissian
We present a novel experiment with the capacity to independently measure both the electron density and the magnetic field of the solar corona. We achieve this through measurement o…
Dispersion Measure Variations and their Effect on Precision Pulsar Timing
X. P. You, G. Hobbs, W. A. Coles +11
We present an analysis of the variations seen in the dispersion measures (DMs) of 20 millisecond pulsars observed as part of the Parkes Pulsar Timing Array project. We carry out a…
