A Census of Southern Pulsars at 185 MHz
Mengyao Xue, N. D. R. Bhat, S. E. Tremblay +7
The Murchison Widefield Array (MWA), and its recently-developed Voltage Capture System (VCS), facilitates extending the low-frequency range of pulsar observations at high-time and…
Spectral Flattening at Low Frequencies in Crab Giant Pulses
B. W. Meyers, S. E. Tremblay, N. D. R. Bhat +6
We report on simultaneous wideband observations of Crab giant pulses with the Parkes radio telescope and the Murchison Widefield Array (MWA). The observations were conducted simult…
Low Frequency Observations of the Subpulse Drifter PSR J0034-0721 with the Murchison Widefield Array
S. J. McSweeney, N. D. R. Bhat, S. E. Tremblay +2
The phenomenon of subpulse drifting may hold the key to understanding the pulsar emission mechanism. Here, we report on new observations of PSR J0034-0721 (B0031-07), carried out w…
A Matched Filter Technique For Slow Radio Transient Detection And First Demonstration With The Murchison Widefield Array
L. Feng, R. Vaulin, J. N. Hewitt +30
Many astronomical sources produce transient phenomena at radio frequencies, but the transient sky at low frequencies (<300 MHz) remains relatively unexplored. Blind surveys with ne…
