Scintillation arcs in low-frequency observations of the timing-array millisecond pulsar J0437-4715
N. D. R. Bhat, S. M. Ord, S. E. Tremblay +2
Low-frequency observations of pulsars provide a powerful means for probing the microstructure in the turbulent interstellar medium (ISM). Here we report on high-resolution dynamic…
The low-frequency characteristics of PSR J0437-4715 observed with the Murchison Widefield Array
N. D. Ramesh Bhat, S. M. Ord, S. E. Tremblay +37
We report on the detection of the millisecond pulsar PSR J0437-4715 with the Murchison Widefield Array (MWA) at a frequency of 192 MHz. Our observations show rapid modulations of p…
First Spectroscopic Imaging Observations of the Sun at Low Radio Frequencies with the Murchison Widefield Array Prototype
Divya Oberoi, Lynn D. Matthews, Iver H. Cairns +67
We present the first spectroscopic images of solar radio transients from the prototype for the Murchison Widefield Array (MWA), observed on 2010 March 27. Our observations span the…
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…
