MWA tied-array processing III: Microsecond time resolution via a polyphase synthesis filter
S. J. McSweeney, S. M. Ord, N. D. R. Bhat +5
A new high time resolution observing mode for the Murchison Widefield Array (MWA) is described, enabling full polarimetric observations with up to 30.72 MHz of bandwidth and a time…
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…
Science with the Murchison Widefield Array: Phase I Results and Phase II Opportunities
A. P. Beardsley, M. Johnston-Hollitt, C. M. Trott +56
The Murchison Widefield Array (MWA) is an open access telescope dedicated to studying the low frequency (80300 MHz) southern sky. Since beginning operations in mid 2013, the MWA…
The frequency-dependent behaviour of subpulse drifting: I. Carousel geometry and emission heights of PSR B0031-07
S. J. McSweeney, N. D. R. Bhat, G. Wright +2
The carousel model of pulsar emission attributes the phenomenon of subpulse drifting to a set of discrete sparks located very near the stellar surface rotating around the magnetic…
A high time resolution study of the millisecond pulsar J2241-5236 at frequencies below 300 MHz
D. Kaur, N. D. R. Bhat, S. E. Tremblay +20
One of the major challenges for pulsar timing array (PTA) experiments is the mitigation of the effects of the turbulent interstellar medium (ISM) from timing data. These can potent…
Improved Techniques for the Surveillance of the Near Earth Space Environment with the Murchison Widefield Array
Brendan Hennessy, Steven Tingay, Paul Hancock +10
In this paper we demonstrate improved techniques to extend coherent processing intervals for passive radar processing, with the Murchison Widefield Array. Specifically, we apply a…
